After the live operation, Lin Yu lay on the hospital bed for a month as usual, and the recovery period of the lungs is generally longer than that of heart transplant surgery, mainly because of the micro-manipulation instruments invented by Lin Yu for organ transplant surgery, which greatly improved the run-in degree between the human body and the artificial lung, which allowed him to recover so quickly.

During the time he recovered, Xu Hai led people to squat for a week, seeing that the other party did not come, so they also evacuated, and they couldn't spend the police force on this matter all the time.

And the police department set up a special anti-crime team, Xu Hai and they led people everywhere to find the reported underworld forces, and this time was also an underground place to crack many gray industries.

Lin Yu was also taken care of by Luo Bing, where is this in the hospital? It's heaven!

Although this is said, Lin Yu still spent a lot of time in reading and research, finally, the hard work paid off, under the strong time difference of the system research institute, Lin Yu finally tried his luck in a year to get some fourth-generation semiconductor materials with good properties - gallium oxide, gallium antimonide.

Gallium oxide is extremely resistant to high temperature and low temperature, which is really an excellent material for aerospace, and the melting point of gallium antimonide is also relatively high, reaching 710 °C, it can usually be used as infrared detectors, infrared light-emitting diodes, transistors, laser diodes and other appliances, these two materials as artificial intelligence chips can have better adaptability with quantum integrated circuits, which can make the computing performance more excellent.

It is worth mentioning that the current chip is still dominated by silicon-based chips, in order to manufacture this kind of chip, it is necessary to use lithography machines, and after Huaxia was jointly sanctioned by foreign countries, lithography machines have become the lifeblood of the development of Huaxia's chip industry, and the most advanced lithography machine is only mastered by Northern Rui in Western Europe, which is EUV lithography machine.

The third-generation semiconductors do not need the world's most advanced 5nm, 7nm and other advanced processes, which is particularly important for Huaxia, in this case, Huaxia's development of the third-generation semiconductors will not be limited by overseas chip equipment, and compared with silicon-based chips, the difficulty of chip process development is much smaller, which is conducive to Huaxia to achieve corner overtaking.

Moreover, compared with the third generation or even the previous two generations, the fourth-generation semiconductor material has the advantages of smaller size, lower energy consumption and stronger functions, and can be better used in optoelectronic devices and power electronic devices under harsh environmental conditions.

With the same chip size, the fourth-generation semiconductor material obviously has better performance.

As long as you are discharged from the hospital, you can hand over part of the content to Sister Xu, and then ask her to help buy materials, conduct another experiment by yourself, and then you can work on the paper.

As for why it needs to be so troublesome, it is because new materials definitely need to be experimented, and if you don't conduct experiments and publish your paper directly, others will definitely doubt the source of your paper's data and results, so it can't be explained.

Just like the key paper on Alzheimer's disease research that was exposed on the Internet some time ago - the academic fraud about amyloid-beta.

Just the weirdness of a picture was directly found to be fraudulent in the paper, which made the project of the three research institutes in the United States for ten years directly a joke, and the special research fund of 3.6 billion yuan in the United States was also lost, but fortunately, although amyloid-beta is fake, this idea is correct.

"Sister Xu, are your funds in place?" Lin Yu dialed Xu Ying's phone, "I want to ask you for something." ”

"I want to borrow your money to buy a little material, gallium and antimony, and some nitride."

"No, I want to make that fourth-generation semiconductor material, I already have some eyebrows, and I feel that the fourth-generation and third-generation gallium chloride have something to do with it, so I want to do it."

"It's okay, you have a channel, I'll transfer it to you, although I don't have a lot of money here, I still have a million."

"Yes, isn't this a coincidence, don't you rest assured that I will be worthy of your cultivation Sister Xu, and I will definitely make two-dimensional semiconductors well!" Lin Yu's tone changed suddenly.

"It's okay, with Bing'er taking care of me, you can rest assured that you don't have to worry about me, after all, I am your eldest disciple!"

Lin Yu and Xu Ying talked for a while, and then hung up the phone.

"Brother Yu, are you inspired again?" Luo Bing's light voice sounded, and she walked in with a lunch box.

"Well, I feel like I'm getting a lot better, and my clogged brain has been opened." Lin Yu took the lunch box in Luo Bing's hand and looked at her affectionately, "Bing'er, thank you, in order to take care of me, you didn't attend classes well during this time." ”

"You know that, too! Why don't you get better soon? ”

"Bing'er, I will be discharged from the hospital tomorrow, the doctors have come to check it, and I am recovering well."

Lin Yu opened the lunch box, today's meal was as light as usual, the staple food was rice, and the dish was fried sweet corn.

"Bing'er, your cooking is getting better and better." Lin Yu took a big sip with a spoon, "My child will be so blessed in the future." ”

"What you kid!" Luo Bing's cheeks were slightly red, and he said something disgusted.

"You are my wife, my child's mother, isn't that a child's mouth!"

"You just like to tease me!" Luo Bing glanced at Lin Yu.

"Okay, okay, Bing'er, have you eaten it, do you want to eat some together?"

"I've eaten it."

When Lin Yu heard this, she reached out and pulled Luo Bing, she didn't stand firmly, and sat directly on the side of Lin Yu's bed.

"Come, open your mouth, I'll feed you."

Lin Yu quickly scooped a spoonful of rice with a spoon and prepared to send it to Luo Bing's mouth.

"I don't want it, I have a habit of cleanliness!" Luo Bing glanced at the spoon that Lin Yu had tasted with disgust.

"Hey, Xiao Nizi is starting to dislike me." Lin Yu put down the spoon, put the lunch box aside, reached out and pulled Luo Bing into his arms, and kissed him directly.

"Hooligans!" Luo Bing got rid of Lin Yu with a red face.

"Hehe", Lin Yu smiled, "Bing'er, you are more fragrant than you cook!" ”

"Eat, I'll ignore you!" Luo Bing handed him the lunch box on the table.

"I don't want it, I want you to feed me personally." Lin Yu prepared inch by inch.

"You think beautifully, I'll feed you with a spoon, forget it if you don't eat it." Luo Bing picked up the spoon.

"Okay" Lin Yu didn't continue to tease her, it would be too much to tease her.

The two of them fed and ate alone, and finished their lunch in silence.

It's already autumn, but the weather in Shangjing is still warm, and the sun is shining on Lin Yu's bedside, making him a little hot, and he doesn't want to move much.

"Brother Yu, then I'll go back to school, there are classes in the afternoon, and I'll come back in the evening." Luo Bing packed up the tableware and said goodbye to Lin Yu.

"Bing'er bye!" Lin Yu beckoned to her obediently.

It's time to continue researching, he sank into the system research institute again, although there has been a breakthrough in the fourth generation of semiconductor materials, there are still many materials that have not been tested, and he has to continue to test to see if there are other suitable materials.
