The object on the experimental table, which is exactly what he got through the experiment, shows a silver-gray color, this kind of monocrystalline silicon compared to the previous monocrystalline silicon, some subtle flaws have disappeared, but it has not yet reached Shang Yiyun's expectations.

In the next time, he continued to do experiments, but he was never able to go further, and the experiment reached this point, Shang Yiyun also knew that it was difficult to continue to improve, so he was ready to take a break and think about what he needed to do next.

When Shang Yiyun was resting, he was also thinking about things, but today's experiment was already successful, after all, he eliminated some subtle flaws through the monocrystalline silicon obtained through the experiment, although it did not meet his requirements, but with this monocrystalline silicon, the production cost would be much lower.

Today, with this kind of harvest, I am already very satisfied, and Shangyiyun also knows that the improvement of silicon materials is not a matter of one or two days.

After coming out of the laboratory, Shang Yiyun went to the place where Li Yunfeng was, although the silicon material crystals obtained today still had some flaws, but compared to the previous ones, they were much better.

When he told Li Yunfeng the performance data of silicon materials, the other party was instantly stunned.

Li Yunfeng didn't expect that it would only take half a day to make such a big improvement, and he could see that the use of this silicon material could save costs and bring greater profits.

At this moment, Shang Yiyun's status rose straight up in Li Yunfeng's heart.

"Shang Yiyun, I know that your ability is relatively strong, but I didn't expect it to be so strong, and it only took half a day to improve the silicon material. ”

At this time, Li Yunfeng's words were full of surprise, which was obviously beyond his expectations.

However, Shangyiyun can do this level, which is also very beneficial to Li Yunfeng.

The people who came with Shangyiyun are working on neutrino communication technology, which is a world-class scientific research topic, and there has been no progress since the previous day.

In the face of this situation, everyone is very helpless, but since they have chosen this path, they can only go on.

Except for Li Yunfeng and a few researchers, they didn't know that Shangyi Yun had made relatively big progress.

After acting in the laboratory for a while, he found that there was still no progress, and Shang Yiyun left the laboratory.

It's been three days since he came to the experimental base, and he has also found his goal, and now he only hopes that there will be a big breakthrough when he leaves.

During the winter vacation for a month, it is impossible for him to stay in the experimental base all the time, as long as there is a big breakthrough, he will leave here.

He is not as good as a researcher in the experimental base now, and he can only be regarded as an intern here, so it is not a troublesome thing for him to leave here.

On the way back, he met Xu Feng.

"How's it going, have you gained anything?"

Hearing the other party's question, Shang Yiyun did not hide it, and directly said the results of the morning.

Although Shang Yiyun spoke as usual and did not mean to show off, Xu Feng heard it, but his heart was difficult to calm down for a long time.

He knew that Shang Yiyun's ability was very strong, and there would definitely be results after a while, but he didn't expect that just after a morning, he would give him such a big surprise.

At this moment, Xu Feng looked at Shang Yiyun's gaze, shining, as if he had found a peerless treasure.

Facing Xu Feng's obviously abnormal eyes, Shang Yiyun now just wanted to beat the other party.

"Damn, what kind of eyes are you? If you look at me like that again, I'm going to do it. ”

After finishing speaking, Shang Yiyun raised his fist, and the meaning was self-evident.

At this time, Xu Feng also knew that he was too anxious, he just felt that Shang Yiyun was very capable, and he didn't mean anything else.

"I really don't mean anything else, I just think that being friends with you is the biggest reward of my visit. ”

For Xu Feng's words, Shang Yiyun also had some feelings in his heart, and he now regarded the other party as a friend.

However, he had some things next, and after chatting with each other for a while, he said goodbye to each other and went to his destination.

Now he was going back to his dorm room and studying what he needed to do next, even though he had a lot of knowledge stored in his mind, there were some missing knowledge that prevented him from going any further.

What he has to do now is to supplement this missing knowledge and then put it into research.

Before that, he had to go to the cafeteria to solve the lunch problem before he could concentrate on studying the literature.

When he came to the cafeteria, others found that there were not many people, and it was right to think about it, if the research reached a critical point, it was common to forget to sleep and eat.

Faced with this situation, Shang Yiyun returned to the dormitory to supplement his knowledge after eating and drinking.

When he looked at some knowledge that he hadn't noticed before, Shang Yiyun fell into deep thought, and after thinking about it for a while, he finally figured out what the problem was.

There was a bang, and he slapped the table in excitement, making a loud noise.

But after the shooting, I immediately regretted it, and I felt pain in my hand, which was completely self-inflicted.

However, he was very happy about the pain in his hands, because he had found a way to continue to improve the silicon material.

Scientific research requires careful observation, because everyone needs to be cautious in their steps, and the slightest mistake may affect the results of the experiment.

After finding the problem, Shang Yiyun wanted to go to the laboratory to do experiments immediately, but after thinking about it, he gave up the idea.

It's already noon, and it's not too late to wait until the afternoon.

After finding the reason, Shang Yiyun was in a very good mood now, lying on the bed and preparing to close his eyes and rest.

Finally, I waited until two o'clock in the afternoon, and went directly to the laboratory, at which time the laboratory was already open, so I could continue to do experiments.

In the process of doing the experiment, Shang Yiyun didn't dare to be sloppy in the slightest, and followed the steps he thought at noon, step by step.

However, although there were no mistakes in the course of the experiment, the results were not satisfactory, and he did not understand why this was the case, so he sat on a stool next to him and pondered.

Suddenly, he looked at the test bench and seemed to understand something.

There will always be failures in experiments, but Shang Yiyun summarizes the reasons for failure in failure after failure.

Finally, a week later, Shang Yiyun looked at the silicon material on the test bench and smiled.

A week ago, although it was a big progress, he was still a little dissatisfied in his heart.

At present, the presence of impurity atoms, vacant clusters, self-intersitive atomic clusters, precipitates of oxygen, carbon or other impurities has all disappeared in this silicon material.

It can be said that in the process of thermal processing, some factors that affect the success or failure of integrated circuits completely disappear.
