Lin Yu, who had just rested for two days after returning to Shangjing, couldn't sit still again, he called Academician Gong and said that he wanted to join the group, because he took advantage of this time to rely on his excellent ability to make the [Neural Fitting Circuit] into a [Neural Network Circuit].

Don't look at the name is not much different, but the connotation is very different.

The latter one is an orderly arrangement of the previous one, while the former one is the constituent unit of the latter one.

"Old Gong, how are you doing?"

"We're going well now, but there are still some problems."

"What's the problem?"

"The materials are not good, according to the existing materials, and then according to the integrated circuits you provide, the quantum computer produced will wear out very quickly."

Before Lin Yu made quantum integrated circuits, the so-called quantum computers could only be regarded as rudimentary forms, and they basically relied on replacing high-efficiency chips to achieve higher computing power.

The resulting quantum computer in this way has a shorter lifespan.

After Lin Yu provides quantum integrated circuits, specific circuits can drive specific power, so the completion of quantum computers is higher, and the life span is also extended to a certain extent.

In fact, the reason for the real short life of quantum computers is the material problem.

I'm afraid that's why the system released me to research a new generation of semiconductor materials.

Lin Yu thought to himself.

The fourth-generation semiconductors have excellent physical and chemical properties, good conductivity and luminescence properties, and have broad application prospects in the fields of power semiconductor devices, ultraviolet detectors, gas sensors and optoelectronic devices.

"Academician Gong, I have a new idea."

"You're not going to take another step and get the materials done, are you?" Academician Gong Yulin guessed.

"Well, I'm going to make fourth-generation semiconductor materials."

"Lin Yu, you have crossed several fields, you have to be single-minded, you can't be professional!"

"But Mr. Gong, my graduate school direction is materials science."

There was a brief silence on the other end of the phone.

Academician Gong listened to Lin Yu's words and was a little silent, was he too superficial?

Or is he, an old hipster who can't keep up with the times?

persuaded him to specialize, but the direction he wanted to study was his major, so what did he persuade?

"Okay, Lin boy, you are going to help our project team clear all obstacles!"

Academician Gong thought about it, this is a good thing, young people are full of energy, wait until the precipitation and precipitation, and then choose the direction of specialization, you can't be too rigid.

But Lin Yu may be destined to disappoint him, because he will cross more majors in the future.

"Old Gong, then I'll be cheeky to join your project team."

"Haha, okay, welcome, just wait for your words."

"Then Gong Lao, do I need to report to the project team?"

"You can come tomorrow, I will tell you the current progress, you also have a careful understanding."

Lin Yu and Academician Gong exchanged two more words, and then hung up the phone.

Why don't I go find Sister Xu now.

Lin Yu thought about it again, it has been the arrival of new students in the past two days, and Sister Xu is probably busy.

He and Luo Bing are both in Beijing, and they just need to wait until the last day of the report to meet their classmates.

At four o'clock in the afternoon, Lin Yu called Xu Ying and learned that she had returned home.

"Sister Xu, I've come to see you. Open the door~" Lin Yu brought Xu Ying some Ganzhou specialties, and in the past two days, he has been obsessed with upgrading topics, and he almost forgot to bring special products.

"Yo! Rare guest. Xu Ying was just washing her hair, and she opened the door for Lin Yu with her still wet hair.

It is said that Lin Yu returned the key to Xu Ying when he moved.

"Sister Xu, come, Ganzhou specialty, this is a big supplement~" Lin Yu handed her two bags of well-packaged boutique specialties.

"Come on, why didn't my Xiaoice come?" Xu Ying smiled and probed behind Lin Yu, but found no one else.

"Bing'er has something to do in the past two days, and she's busy."

Xu Ying pretended to be angry, "Who are you?" I don't know! As he spoke, he closed the door.

"Don't, Sister Xu, I have something to look for you." Lin Yu pressed his foot against the door and said with a hippie smile.

"It's not in shape!" Xu Ying put away the pretense of being unkind and took him into the house.

"Tell me, what do you want me to help you do?" Xu Ying sat on the sofa, "I know that if you don't bring Bing'er, you will have nothing to do and go to the Three Treasures Palace." ”

"Sister Xu, I just miss you, can't I come to see you?"

"Hey, the sun is coming out in the west, and I've always been the only one to take care of you, you little fool still know to come to see your empty nest sister at home?"

Lin Yu didn't know how to answer, knowing that she was complaining that she didn't talk to her during the time she was out, which made her feel like an empty nester.

Xu Ying looked at the stunned Lin Yu, and laughed out loud, "Luo Bing said that you are romantic, and I just thought that your wooden head was a little grown, but it turned out to be so unfunny." ”

"Okay, let's talk, what do you think?"

"Hehe", Lin Yu smiled embarrassedly, "Sister Xu, I want to make that fourth-generation semiconductor material." ”

After speaking, Xu Ying looked at him with some incredulity, "Changed sex?" Why did you suddenly remember that materials science is your major this time? ”

"I just suddenly want to make this thing, especially Academician Gong also needs this material."

Lin Yu told Xu Ying about the plight of the artificial intelligence project team led by Academician Gong.

"Okay, Old Man Lin Yugong's team can also get in."

"No way, I'm excellent!"

"Okay, don't be poor." Xu Ying thought about it carefully, "Do you want to work on this project with us?" ”

Lin Yu nodded.

"Yes, according to the existing theory, the fourth generation of semiconductors has excellent physical and chemical properties, good conductivity and luminescence performance, and it is an excellent choice to make power semiconductor devices."

Ying Xu is a doctoral supervisor of materials and biomechanics, and has a very cutting-edge understanding of materials science.

"At present, the main material systems with development potential to become the fourth generation of semiconductor technology mainly include: gallium antimonide and indium arsenic compound semiconductors with narrow band gaps; ultra-wide bandgap oxide materials; Other low-dimensional materials such as carbon-based nanomaterials, two-dimensional atomic crystal materials, etc. ”

"If you want to make electronic components that match quantum computers, then we have to measure the properties of each of these materials one by one and pick the best one."

"It's a time-consuming and labor-intensive job." Xu Ying said so much, picked up the water cup and took a sip.

She got up and went to the kitchen to add the freshly boiled hot water to the cup in front of Lin Yu, "So I don't like to engage in materials, but why didn't my mother think about choosing this major?" ”

"Of the four major sinkholes of biochemical ring materials, my mother accounted for two, and I really wanted to slap myself back then." The more Xu Ying spoke, the more energetic she became.

Lin Yu didn't dare to persuade her, especially when she called herself "old lady", according to past experience, Sister Xu's combat power at this time was off the charts.

But he still has to say that the salary of a top talent in the industry like Sister Xu is still very good.
