Chapter 254 The Value of Trial and Error

After lunch, Chen Zhou and Zhang Yifan took a brief rest to digest food and refresh their minds.

Long hours of work awaited them in the afternoon.

Taking advantage of this time, Chen Zhou took out the set of wrong questions from his backpack.

As expected, the set of wrong questions is only one word, many!

All the documents and data that Chen Zhou has read are all recorded on it.

Before finding a suitable preparation process, as Chen Zhou read more and more documents, more and more content will be recorded in the wrong question collection.

But if Chen Zhou finds a suitable direction, the wrong question set will become a place for trial and error.

Moreover, in this direction, with the improvement of the preparation process, the content originally recorded on the wrong question set will gradually disappear.

If and only if Chen Zhou perfectly solves the problem of preparation technology, all the content on the wrong question set will disappear.

It's just that Chen Zhou doesn't have extravagant hopes for this. How easy is it to have a perfect preparation process?
He only hopes to find a relatively perfect preparation process at present to solve the immediate problem.

After all, Chen Zhou still understands the principle of eating one bite at a time.

After analyzing the data on the wrong question set, Chen Zhou closed the wrong question set and closed his eyes.

After 10 minutes, he opened his eyes and sat down in front of the computer.

Research continues.

"Higher microwave power density can strengthen the decomposition and ionization of reaction gases, increase the concentration and activity of each reaction group, promote growth, and improve growth efficiency..."

"In addition to the influence of these reaction gas parameters, there is also the influence of the MPCVD device itself. How to choose the shape of the substrate support to reduce power loss and improve diamond production efficiency?"

Chen Zhou looked at the compiled information in front of him, and these questions kept flashing through his mind.

He habitually took a pen and tapped on the draft paper, and when he had an idea, he would write it down.

Wait until you have read all the material before organizing your thoughts.

"From the previous experimental data, the MPCVD method can prepare diamond thin films of tens of nanometers, and can also prepare diamond thick films on the order of millimeters."

"However, this requires a larger diamond substrate, and in subsequent doping experiments, if heteroepitaxial growth is difficult, it will also make it difficult to prepare large-scale, high-quality diamond single crystals."

"All in all, it is still a suitable parameter for preparing diamond, which is difficult to choose."

After Chen Zhou sorted out the documents that Zhang Yifan and Shen Jing had sorted out, he began to sort out what he had written on the draft paper.

This thing can be said to be the essence of extraction.

While combing, Chen Zhou thought about the corresponding solution.

"The volume fraction of CH4, working pressure, microwave power, substrate temperature, etc., can only confirm the approximate range, and cannot accurately determine the experimental parameters..."

Chen Zhou wrote one draft paper after another, all of which were trial and error.

After a long time, he put down his pen, turned to open the collection of wrong questions, and looked through it carefully.

The value of trial and error of wrong question sets is here.

If you go to ordinary people, the cost of trial and error is experiment after experiment.

From the data fed back from the experiment, gradually improve the parameters of the experiment, and approach the reasonable experiment goal step by step.

Among them, the cost of trial and error, whether it is time, energy, money, or equipment, is a huge consumption.

But for Chen Zhou, the set of wrong questions saved the steps of the experiment, and also saved a lot of substantial trial and error costs.

This is actually what Pan Shiyan has always been puzzled about.

It was getting dark outside.

When Peng Fei and Shen Jing appeared at the door and knocked on the door, Chen Zhou and Zhang Yifan came to their senses.

After rubbing his temples, Chen Zhou got up and went to open the door.

Seeing the two people at the door, Chen Zhou smiled and asked, "How is today?"

Peng Fei replied: "The co-doping experiment ended as planned. I have to go back to the laboratory later to keep an eye on the collation of the experimental data."

"Work overtime at the research institute at night?" Chen Zhou looked at Peng Fei in surprise. Is he planning to sort out the 10th set of data tonight?
Just as Chen Zhou thought, Peng Fei said with a smile: "You're trying to get someone to help you, and you're staying up all night to study, so we can't hold back, can we?"

Chen Zhou smiled embarrassedly. In fact, he wanted to say that there is really no rush for the 10th set of data.

Because, even if it was sorted out, he didn't have time to study it these two days.

At least he had to wait until he came up with a satisfactory diamond film preparation process and let the 43 Institute pass the experimental device to verify it.

He will start the doping experiment.

"By the way, you will continue to work in the hotel tomorrow?" Peng Fei asked again, remembering that the documents Chen Zhou had given him had not been sorted out.

Chen Zhou thought for a while and said, "I should still be in the hotel tomorrow. Well, if you have sorted out the data of the 10th group, then the senior will go to the 43rd school again to integrate all the data."

"Okay, then I understand. I'll hurry back to the office now." After Peng Fei finished speaking, he left the hotel.

Chen Zhou looked at Peng Fei's leaving back, hesitated to speak, he really didn't know what Peng Fei understood?

Shen Jing at the side finally said with a tired look on his face: "Chen Zhou, you won't really let me go to the 43rd by myself tomorrow, will you?"

Chen Zhou asked back: "Have you finished processing today's data?"

Shen Jing nodded: "Hurry up, it's finally done."

Chen Zhou glanced at Shen Jing, and said solemnly: "That's it. Senior, there is only one set of data left tomorrow, and it will be very fast. Finally, this set of data will be settled, and then a little integration will be very fast. .”

"Uh..." Shen Jing said hesitantly, "This workload is not small."

Chen Zhou: "Senior, I like you."

Shen Jing: "..."

After a while, Shen Jing said softly: "I haven't finished sorting out the documents you sent."

Chen Zhou smiled, did not answer the question, and turned to look at Zhang Yifan: "Let's go, Yifan, let's eat."

Hearing this, Zhang Yifan raised his head and glanced at Chen Zhou in confusion. The topic between the two of them was a bit jumpy, wasn't it?
Isn't Shen Jing complaining that he has too much work and is already too busy?

How does this talk about eating?

Chen Zhou seemed to see what Zhang Yifan was thinking, and said with a light smile, "Enough to eat and drink, continue to the second half!"

Zhang Yifan: "..."

Shen Jing: "..."

During the meal, Chen Zhou received a document from Yang Yiyi.

Yang Yiyi's work over there was half over, so she first sent over half of the materials that had been sorted out.

Chen Zhou opened it and took a look, then made a video call to Yang Yiyi.

In this group of six, probably only Yang Yiyi could keep up with his thoughts and ideas.

It can also provide timely and accurate feedback of useful literature information.

However, Chen Zhou is not in a hurry, after this running-in.

If there is an opportunity to jointly research topics in the future, it will be much better then.
