"Yes, your game is a good game, it sold 500,000 copies in three months, this is the fastest game ever to reach this sales number, it has brought nearly 20 million revenue to Fairchild Entertainment, but it still can't save Fairchild's crisis, after all, entertainment is not Fairchild's main business, semiconductors are its life-"

The reporter who opened his mouth obviously knows more about Fairchild Entertainment, but these are of little significance to Zheng Jianguo, he doesn't know what semiconductors are, and he doesn't know that Fairchild, a company that represents the development history of Silicon Valley, belongs to the "West Point Military Academy" in the electronic technology industry, and it is not that he doesn't know the importance of semiconductors in the future.

On the contrary, Zheng Jianguo is very aware of these things, and even he knows that Intel and AMD, which are unknown at this time, will become global giants in the future, and the founders of these two companies are founded by leaving Fairchild Semiconductor, and in a few decades, semiconductors will enter thousands of households and turn the earth into a village.

But just like this, Zheng Jianguo didn't dare to contact this company too much, Wang An's computer boss is an authentic American, he studied and worked in the United States forty years ago to create an office company, and even cut off contact with China for forty years, as if those no longer existed when he declared it, but even this did not live to thirty years later-

Zheng Jianguo doesn't know how this computer company is cold, but he knows that what he can do at the moment is to make a fortune with the seemingly "lucky" opportunity, and by the way, he will deduct an enviable luck from his head - silver is like this, and so is gold.

The former is Van Dailing who discovered the conspiracy of the Harant family, and the latter is a hedging investment that ordinary investors will choose, of course, this is based on the fact that the price of gold will not fall into negative numbers and its own value, the purpose is that Zheng Jianguo vaguely remembers the outbreak of the Iran-Iraq war at the end of the year, and the rise of oil, along with a wave of gold.

And this is also the maximum that Zheng Jianguo can do, the sixteen-year-old young man has made a lot of money by investing in the halo of a scholar on his head, although this is somewhat beyond people's imagination, but it is also within the normal range, but if he mixes with semiconductors involving the lifeblood of industry at this time, this risk is countless times greater than the success of the research he is doing: "It's a pity that I have only been in contact with solid state physics for a long time, and the semester assignment assigned by my basic physics teacher is to do a physics experiment, can you believe it?" It's okay to take a mirror and do a refraction experiment with a basin of water—"

"Isn't that a rainbow experiment?"

A reporter said it, Zheng Jianguo tilted his head and raised his eyebrows as if you had answered correctly: "Yes, even the rainbow experiment is fine, maybe Professor Thomas thinks that those of us who go to elective classes are just to relax——"

"Zheng, what experiment are you going to do?"

A reporter put away his notebook and asked with curiosity on his face, and then looked at the reporter who said the rainbow test earlier and smiled: "Do you also want to do a fun experiment for junior high school students or elementary school students?"

"No, I'm going to grind graphite-"

Zheng Jianguo raised his eyebrows and shook his head and said, and the reporters laughed: "Grinding graphite, this is also an experiment——"

"Is it the pencil graphite?"

"Graphite haha-"

The reporters dispersed in twos and threes, Zheng Jianguo carried the bag into the teaching center, and found the secretary of the department, Belinda, who had said something in the morning, and saw that she was shocked and said, "You, how do you need the college to help you?"

"I want to live in the academy, and I can pay for it. ”

Zheng Jianguo spoke, and Belinda immediately nodded in response: "This is no problem, I can tell the management office, if you need to spend it, I will tell you, how did you study in Massachusetts, are you sure to get B+?"

"There's still a need for an experiment over there, and I'm sure B+ is fine, so I'll leave it to you about the accommodation, Belinda. ”

Although Zheng Jianguo's identity is a little detached, the conditions and requirements given by the school are also equal, and you can choose the courses you want to take at will, but you need to pass the assessment of the selected course.

Fortunately, after Zheng Jianguo entered Harvard Medical School, the difficulty he faced was not the absorption of professorial knowledge like other medical students, but the matching of the Chinese in memory with the Chinese-style English he had learned, and it was easy to pass for most of the year.

Of course, in Zheng Jianguo's view, the main reason why he didn't feel the pressure of learning at this time was that the change in his memory of medical equipment based on the development of computer technology as the core had not yet arrived.

In view of the uncertainty of what he remembers, Zheng Jianguo mostly listens more and watches less when he studies, plus he also carries a video camera, so he has not made any friends after more than a month of classes, but he does not know as many people as he knows in the elective courses at MIT.

After reporting that he was going to move, Zheng Jianguo didn't forget the bad words of the two policemen, but fortunately, the place he was moving to was a school, and the geographical location did not leave the urban area of Greater Boston, and it was only a twenty-minute drive from the Massachusetts Institute of Technology-

Crossing the Harvard Bridge over the Charles River with the car closed the window and the car with vigilant eyes, Zheng Jianguo also entered the territory of the Massachusetts Institute of Technology, found the address written in his pocket and touched the front of the No. 36 teaching building, and saw his test partner looking at the door, and saw his car appear and quickly arrived in front of the car: "Zheng, why did you come, our laboratory was almost occupied——"

The one who spoke was a white-toothed brother, and he was also a classmate that Zheng Jianguo met when he took a basic physics course, Brady Binns of Harvard Law School, and he was the only two alumni of Harvard University who had applied for basic physics, so he became a teammate in the assessment group test at the end of the course: "If Celia hadn't reported your name, it would have been taken up." ”

Celia Keynes is a top student majoring in chemistry at MIT, a genius girl who is only one year older than Zheng Jianguo, and is the only one in the trio who is more normal for the elective of basic physics.

After all, compared with the law school and medical school of the two, the chemistry major is closer than basic physics, but when Zheng Jianguo found a good place to park and arrived at the door of the building, Brady said again: "Celia brought her sister over, saying that she is a doctor of solid state physics, considering that we have a deep knowledge of experiments, and it is used to help us conduct experiments——"

"What's deep, let's just observe, right?"

Zheng Jianguo's heart jumped and said it as unintentional, and then found that Brady's face was full of question marks and said: "Observation itself is an experiment, is it possible that you must come out with the results?"

"Huh? You're right—"

Brady blinked his big white eyes like swallowing a fly, and quickly caught up with Zheng Jianguo's footsteps: "Of course it's good to have results, right?"

"You don't look at what kind of experiments we do, and the results will be terrible. ”

Zheng Jianguo shrugged his shoulders and arrived at the elevator entrance, and Brady next to him once again showed a little face that swallowed a fly, and nodded quickly: "Yes, yes, if we find out, I feel like we can change careers——"

"You're from law school and you're going to transfer to engineering?"

Pretending not to care, Zheng Jianguo stepped into the elevator that had already explored the terrain, Brady followed into the elevator and pressed the fifth floor button, looked at the beating floor numbers and said: "I said if you find it, but it's no problem if you can't turn around, it's a big deal to study two majors at the same time——"

“——”

In his heart, he silently paid the highest tribute to this white tooth brother, Zheng Jianguo remembered that he was now at the Massachusetts Institute of Technology, the highest university at the top of the pyramid, and the university that all high school students in the world dreamed of, of course, he was not stunned when facing this unashamed white tooth brother: "You don't plan to go to medical school after graduation-"

"You're not kidding—"

Brady glanced at Zheng Jianguo with a shocked face, shook his head quickly, and said, "Then I'd rather take three more professional degrees-"

"Huh. ”

When Zheng Jianguo smiled, the elevator door opened, and Brady stepped out first, just in time to see Celia standing in the corridor, tall and thin wearing a sweatshirt, with thick eyebrows and big eyes like a boy more like a girl: "Zheng, you are finally here, if you don't come again, we should go to you." ”

"Something happened to the accommodation, but it's okay now, let's start now?"

Zheng Jianguo's camera and battery pack were thrown in the car, he didn't say anything else except his notebook at this moment, the white glass door behind Celia opened, and a girl who was obviously much more mature appeared next to her: "Coming?

"Let's start by grinding graphite—"

Zheng Jianguo looked at the girl and then looked at Celia, and the latter spoke: "This is Ullica sent by the teacher after learning that we are going to do graphite experiments, she is Professor Thomas's doctorate, and this year's graduation thesis is graphite-"

"Chemical Reduction Separation of Graphite Oxide by Hydrazine Hydrate and Divalent Iron Salt", this is my graduation thesis this year, which has been defended. ”

Ulrika's eyes were full of curiosity on the high bridge of her nose, and she was not surprised by the three curious babies' cross-border exploration: " Since the German scientist Schafhaeutl in 1840 believed that the interlayers of graphite are bound by the weak Van der Waals force, so that small molecules of acid or alkali metals can be inserted into the interlayer of graphite to prepare graphite interlayer complexes, countless scientists have only obtained a thin layer of graphite with a thickness of 46 nanometers for more than a century, and you may not know how many parts of a hair is 1 nanometer——"

"One in sixty-thousand!"

I don't know when Brady, who arrived next to him, raised his hand and said, and then found that Zheng Jianguo and Celia were looking at him, and couldn't help but shrug his shoulders and said, "What, did I say something wrong?"

"No, you're right, it's one in sixty thousand. ”

Ulrika raised an eyebrow, then looked at the entrance next to her and said, "Okay, we can change our clothes and enter the lab, Brady, can you grind graphite?

"Okay, no problem, I'll leave this to me-"

Brady looked at Ulrica with excitement on her face, but including Zheng Jianguo, she could see that his eyes moved up and down a lot on Ullica's face, so she turned around and entered the changing room and began to put on dust-free clothes, and only after the four of them entered separately did Ulrica take out a thin piece of graphite the size of a thumb from the white material cabinet: "There is a grinder on the table, I'll teach them both to tune the microscope and spectrometer, you are ready to say-"

"I didn't expect to look for more than 140 years and I couldn't find it, but I remember that there is a theorem or something that proves that two-dimensional materials cannot appear in nature, right?"

Taking the thin layer of graphite and feeling its thickness with his fingers on the fingers, Brady's eyes swept over what looked like a few sheets of paper, and he saw Ulrica nodding and said in surprise: "You have done your homework in advance? You are describing the provable Mermin-Wagner theorem based on statistical physics, which holds that crystals are composed of perfectly ordered particles with a continuously symmetrical atomic structure.

But the Mermin-Wagner theorem of 1966 shattered this idea: in one- and two-dimensional atomic structures (e.g., atomic chains or thin films), it is impossible to have perfectly arranged particles for a long time.

Therefore, some scientists think that it is impossible for two-dimensional materials to appear in nature at room temperature, but the curiosity of scientists cannot be stopped.

"Well, I wanted to see, but I'm here to do experiments-"

Brady turned around and looked at the graphite sheet in his hand and shook his head and said, just when he wanted to reach out to turn on the switch of the grinder, Ulrika's voice came from behind him: "Wear goggles, gloves and masks, you don't want to inhale molecular-level graphite into your lungs, believe me, you definitely don't want to see advanced pneumoconiosis patients, I only warn you once, no matter what grinder you turn on, remember to protect yourself and protect yourself." ”

"Okay, okay, I'll put it on right away. ”

Brady tilted his head without looking back, picked up the protective goggles and mask next to him and put them on, then looked left and right at the stool under the grinder table, and immediately pulled it out and sat in front of him and turned on the strong light above, seeing that all the preparations that could be made were done, he turned on the switch in his heart and pressed the thin graphite sheet in his hand on the high-speed rotating grinder.

It's just that the graphite sheet that Brady expected seems to be very hard and hard, and after grinding it, it will be withdrawn to see that there are only slight scratches on it, so he turned his head to look at the three people who were surrounding the microscope behind him, and then turned around and pressed the graphite sheet on the grinder: "Ahhh

"When Brady is finished, we can use this 300-nanometer thermal silicon oxide wafer as a substrate to observe. ”

Ullica followed Zheng Jianguo's gaze and looked at Brady behind her, and said, as if she remembered something, she said: "The polished graphite ash should be glued off with tape, so that you can see what the surface to grind is like-"

"Oh, okay!"

Brady's voice came, and Ulrica also looked back at Zheng Jianguo and Celia and said, "Of course, before that, our preparation is to put these substrates into an ultrasonic machine with acetone and absolute ethanol and clean them for twenty minutes to prevent the surface from being contaminated-"
