It's easy to come up with an idea, but it's incredibly difficult to turn it into reality.

On the computer, all the relevant literature of the DAPCVD method and the MPCVD method is opened.

In front of the computer, Chen Zhou held a pen and wrote scratch paper.

The differences between the two methods, the advantages and disadvantages of the two methods, the constraints of the two methods, and the possible compatibility of the two methods......

Chen Zhou listed them all one by one.

"In addition to the microwave power and gas pressure, the temperature of the substrate is not uniform, which also affects the deposition rate of the diamond film and makes the quality of the film deteriorate......"

"Too fast deposition rate will also affect the uniformity of the diamond film, resulting in poor film quality......

Chen Zhou's mind kept flashing through the factors that affected the deposition rate and the quality of the film.

Glancing at what he had written on the scratch paper, Chen Zhou muttered: "Contradictory ......"

That's right.

There is a contradiction between the deposition rate of diamond films and the quality of the films.

The deposition area of the rapidly deposited diamond film is limited to a few millimeters.

This results in poor uniformity and low quality of the film.

"Forget it, it's not too early, let's go to bed first......"

Gently putting down the pen, Chen Zhou turned off the computer, got up and went to wash.

Halfway through, he suddenly remembered something.

"It's over, it's over...... It's a dead ......."

Chen Zhou muttered, ran quickly to the table, picked up his phone and glanced at it.

Yang Yiyi didn't send a message.

Chen Zhou thought that he had made a mistake, and confirmed it again.

Yang Yiyi really didn't send a message......

Chen Zhou glanced at the time, it was already one o'clock.

After thinking about it, he opened the chat interface and began to send a message to Yang Yiyi:

[Yiyi, I'm sorry, I'm really busy today, and I asked Yifan to help sort out the information at night, I'm sorry I forgot to send you a message. 】

[The time spent in Luzhou may be longer than I expected, I will solve the matter as soon as possible and return to Yanda.] 】

[Yiyi, good night. 】

Looking at the message sent over, Chen Zhou twitched the corners of his mouth slightly: "I don't know if such a late explanation is useful?"

This time it was indeed he who forgot.

Before coming, Yang Yiyi emphasized that after settling down in the place, she would make a video call.

It turned out to be settled, but it was already one o'clock in the middle of the night......

Just when Chen Zhou was entangled, the mobile phone rang.

Yang Yiyi sent a video call invitation.

Chen Zhou was slightly surprised, but immediately pressed answer.

On the mobile phone, Yang Yiyi's picture appeared.

On Yang Yiyi's side, the lights in the dormitory had been turned off, and she was lying on the bed, illuminated by the light of the desk lamp.

Seeing Yang Yiyi waiting for him with headphones, Chen Zhou was slightly moved.

This girl, I'm afraid she hasn't been waiting for herself, right?

Chen Zhou was just about to speak, but Yang Yiyi had already lowered his voice and said first: "Are you busy just now?"

Chen Zhou nodded: "I've been sorting out the subject materials, and I just planned to take a bath......"

Yang Yiyi looked at Chen Zhou, and said with a gentle look in her eyes: "You, you don't know the time when you're busy, I originally thought that you only went today, at least you won't fall into the subject tonight, but as soon as you go, you took on a project by yourself......

Chen Zhou was slightly stunned, and immediately glanced at the muted chat group.

This Zhang Yifan talked about the preparation process of diamond film in their chat group......

After thinking about it, Chen Zhou laughed softly: "It's all a whole subject, not counted." ”

Yang Yiyi didn't speak, just looked at Chen Zhou.

Chen Zhou didn't know what to say for a while.

Speaking of which, not counting the winter and summer vacations, this is the first time the two have separated.

After a while, Yang Yiyi pouted, and then said: "Okay, if you want to change the preparation process, then do it, I believe you can do it." But now you have to go to the shower and sleep, and you have to rest well to overcome the problem!"

Hearing Yang Yiyi's words, Chen Zhou smiled and nodded vigorously: "Well, I know, you can go to bed quickly." ”

Yang Yiyi tried her best to lower her voice: "I'll wait for you to take a shower and sleep together, I'll turn off the lamp first, I'm afraid of making noise to Li Jing and them." ”

Chen Zhou: "Then I'll go and come back quickly, you wait for me." ”

Yang Yiyi: "Okay." ”

Chen Zhou put his phone aside, walked into the bathroom quickly, and began to wash.

There is a characteristic of boys taking a bath, that is, fast!

Wet your hair and body with the showerhead, wipe your head with shampoo, wipe your body with shower gel, rub your hands together, and you're done!

As for facial cleansers and the like, Chen Zhou has never used them.

After all, someone as handsome as him usually doesn't need this thing.

Dry his hair and body, brush his teeth again, and in five minutes, Chen Zhou was done.

However, worried that his voice would make Yang Yiyi noisy, Chen Zhou's pace slowed down a lot after he got out of the bathroom.

When he picked up his phone again, Yang Yiyi on the other side was already asleep.

Following.

Chen Zhou got up early and jogged in the morning as usual, and came in strict accordance with the previous rules of life.

When he went for a morning run, Chen Zhou unconsciously thought of the mobile phone video that he had been driving all night.

Yang Yiyi's sleeping appearance, he has recorded the whole process.

Chen Zhou just wants to say, it's really cute, it's good-looking, and it's very attractive......

At eight o'clock in the morning, Peng Fei appeared at the hotel and had breakfast with Chen Zhou.

He's here to pick them up.

During the research period, he was arranged by Dr. Wu to work part-time as a "tour guide" for Chen Zhou and Shen Jing.

During the meal, Chen Zhou asked: "Peng Gong, today's formal experiment is to doping diamond with p-type and n-type stones?"

"That's right, two experiments are going on at the same time today. Peng Fei nodded, and then said regretfully, "But it's a pity that we don't have enough manpower, otherwise we would have done p-type doping, n-type doping and co-doping together." ”

Hearing this, Chen Zhou smiled and asked instead, "Yesterday, Dr. Wu said that this is the last set of doping experiments, is that so?"

Peng Fei glanced at Chen Zhou and explained, "Dr. Wu does not mean that this is the last set of experiments on this topic, but that this is the last set of experiments conducted according to the experimental design in the early stage. ”

Worried that Chen Zhou didn't understand, Peng Fei added: "Our research is generally to complete the designed experiments first, then conduct experimental analysis, improve the experiments, and then redesign the experiments. Now it's just the experiments that we've just designed. ”

Chen Zhou nodded, and asked again, "How many sets of experiments were carried out in the early stage?"

Peng Fei looked at Chen Zhou with some surprise: "Didn't Dr. Wu give you the experimental data yesterday?"

Chen Zhou shook his head: "Not yet." ”

Peng Fei frowned slightly, it stands to reason that Chen Zhou and Shen Jing came to help with data analysis, why didn't Dr. Wu give them the data?

Peng Fei didn't figure it out, but he felt that it shouldn't be a big deal, maybe Dr. Wu had his own considerations.

He said directly: "There were 9 groups of experiments in the front, and this is the 10th group. Maybe Dr. Wu is planning to give you the experimental data at once. ”

Chen Zhou thought for a while and said with a smile: "Maybe, if the data is in hand, then Senior Shen Jing and I will be even busier." ”

Peng Fei smiled, but did not speak.
