After lunch, Chen Zhou and Huang Jiayi took a brief rest to eliminate food and nourish their spirits.

There are still long hours of work waiting for them in the afternoon.

Chen Zhou took advantage of this time and took out the wrong question set from his backpack.

As expected, the set of mistakes is just one word, many!

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

Before finding a suitable preparation process, as Chen Zhou looked at more and more literature, there would be more and more content recorded in the wrong question set.

But if Chen Zhou finds a suitable direction, the problem 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, when Chen Zhou solves the problem of preparation process perfectly, all the content on the problem set will disappear.

It's just that Chen Zhou doesn't have extravagant hopes for this, how easy is it to talk about a perfect preparation process?

He only hopes to find a relatively perfect preparation process at the moment to solve the problem at hand.

After all, Chen Zhou still understands the truth that rice should be eaten 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.

Ten minutes later, he opened his eyes and sat down in front of the computer.

Research continues.

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

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

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

He habitually took a pen and lit it on scratch paper, and when he had an idea, he wrote it down.

Wait until you've read all the information and then organize these ideas.

"Judging from the previous experimental data, the MPCVD method can prepare diamond films of tens of nanometers, and can also prepare thick diamond films of millimeter size. ”

"However, this requires a large diamond substrate, and in subsequent doping experiments, if heteroepitaxy generation is difficult, it will also lead to difficulties in preparing large-size, high-quality diamond single crystals. ”

"All in all, it is difficult to choose the right parameters for the preparation of diamonds. ”

After Chen Zhou re-sorted out the documents and materials compiled by Zhang Yifan and Shen Jing, he began to sort out the content he wrote on the scratch paper.

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

While combing, Chen Zhou thought about the corresponding solutions.

"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 scratch paper after another, full of trial and error.

After a long time, he put down his pen, turned to open the wrong problem book, and looked at it carefully.

The value of trial and error in the wrong question set is here.

If you are isolated from ordinary people, the cost of trial and error is one experiment after another.

From the data fed back from the experiment, the parameters of the experiment are gradually improved, and the reasonable experimental goal is approached step by step.

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

But in Chen Zhou's case, the problem set saves the steps of the experiment and also saves a lot of substantial trial and error costs.

This is actually what Pan Shiyan has always wondered 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 back to their senses.

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'll have to go back to the lab in a moment and keep an eye on the data collation. ”

"Working overtime at night?" Chen Zhou glanced at Peng Fei in surprise, is this planning to sort out the 10th group of data tonight?

As Chen Zhou thought, Peng Fei said with a smile: "You are shaking people to help, and you are staying up all night to study, we can't hold back, right?"

Chen Zhou smiled embarrassedly, in fact, he wanted to say that this 10th group of data is really not in a hurry.

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

At least he has to wait until he comes up with a satisfactory diamond film preparation process and asks the 43rd Institute to verify it through the experimental setup.

He will start to work on doping experiments.

"By the way, tomorrow you will continue to work in the hotel?" Peng Fei remembered that the documents and materials assigned to him by Chen Zhou had not been sorted out, so he asked again.

Chen Zhou thought for a while and said, "It should still be in the hotel tomorrow, well, if you sort out the 10th group of data, then the senior will go to the 43rd Institute again and integrate all the data." ”

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

Chen Zhou looked at the back of Peng Fei leaving, and stopped talking, he really didn't know what Peng Fei understood?

Shen Jing on the side, at this time, finally said with a tired look on his face: "Chen Zhou, you won't really let me go to the forty-three institutes alone tomorrow, right?"

Chen Zhou asked rhetorically, "Is all the data processed today?"

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

Chen Zhou glanced at Shen Jing and said solemnly, "That's not it." Senior, there's a set of data left tomorrow, soon. In the end, this set of data is done, and then it is slightly integrated and integrated, and it will be very fast. ”

"Uh......" Shen Jing said hesitantly, "this is not a small amount of work." ”

Chen Zhou: "Senior, I'm optimistic about you." ”

Shen Jing: "......"

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

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

When Zhang Yifan heard this, he raised his head and glanced at Chen Zhou a little confused, the topic of these two people jumped a little bit?

Isn't Shen Jing complaining that he has too much work and can't be busy?

How does this mean eating?

Chen Zhou seemed to see what Zhang Yifan was thinking, and said with a chuckle: "Eat and drink, continue the second half!"

Zhang Yifan: "......"

Shen Jing: "......"

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

Yang Yiyi's work was half over, and she first sent half of the sorted out information.

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

In this six-person group, probably only Yang Yiyi can 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 run-in.

It would be much better if there were opportunities for joint research in the future.
