Xueba starts with change

Chapter 250 Time is tight
There are currently 9 sets of experimental data.

According to the current progress of the experiment, after the end of the co-doping experiment tomorrow, at least the morning of the day after tomorrow, the 10th set of data will be sorted out.

In other words, Chen Zhou and Shen Jing currently have almost two days to process the 9 sets of data at hand.

Based on this time, Chen Zhou made arrangements for his and Shen Jing's work arrangements.

Looking at the plan written on the draft paper, Chen Zhou frowned slightly.

"This won't work. If you drag it on, wait for the experiment to verify, and then adjust the direction of the experiment, it will take too much time..."

Chen Zhou obviously didn't have that much time.

Not to mention the half-month time limit required by the hidden mission, Chen Zhou alone set a limit of one week for himself.

"It seems that we have to seek help again..."

Thinking of this, he sent another message to Zhang Yifan, asking Zhang Yifan to help him find the relevant data of the diamond doping experiment.

Through the last time the experimental data of the particle accelerator was reversed, Chen Zhou deeply realized how important it is to stand on the shoulders of "giants".

Of course, the giant here refers to the huge amount of literature.

Zhang Yifan replied with an "OK" expression.

Seeing this expression, Chen Zhou smiled slightly.

Before leaving, a big meal must be arranged as a reward!
Chen Zhou opened the chat box with Yang Yiyi again, and sent a message.

[Yiyi, are you busy with Dean Yang's experiments recently? 】

Not long after, Yang Yiyi replied to the message.

[Not busy, now Senior Sister Peng Jia and the others have adopted our method and have already shared the work. 】

After reading the message, before Chen Zhou could reply, Yang Yiyi sent another message.

【how?Do you need my help, happy? 】

Chen Zhou smiled and clicked on the phone screen, returning to:
[Maybe stay up late with me. 】

As soon as the message was sent, Yang Yiyi came back.

[It's okay, the two of us will endure together, saving one person from worrying about the other.You send me the information? 】

[Still at 43, I will send you back at night. 】

【it is good. 】

Yang Yiyi successfully joined, and Chen Zhou's small team was upgraded to a four-member team.

Putting away the phone, Chen Zhou smiled and basically arranged everything.

Immediately, he looked at Shen Jing: "Senior, shall we open on June [-]rd?"

Shen Jing looked at Chen Zhou in surprise: "Are you busy?"

Chen Zhou was taken aback for a moment, then smiled lightly and said, "You are six, I am three."

"Uh..." Shen Jing was confused now.

He originally thought that Chen Zhou was going to handle two-thirds of the data by himself, but he didn't expect him to be responsible.

Chen Zhou didn't explain too much, just said: "Senior, how is it?"

Shen Jing looked at Chen Zhou and nodded slowly.

"Okay, trust me, we can go back sooner." Chen Zhou said casually, and began to write the plan on the draft paper.

Hearing this, Shen Jing thought for a while, and immediately understood what Chen Zhou meant.

It is said that he is responsible for two-thirds of the data analysis, but in fact, Chen Zhou may have to do much more work than him.

Thinking of this, Shen Jing turned his gaze to the computer screen in front of him and started to work.

He still wanted to help Chen Zhou share more.

Otherwise, when I returned to Yanda, Wu Xiping asked, what have you all done?

How dare he say...

Only responsible for the analysis of 3 sets of data, Chen Zhou's current work pressure has been relieved.

In this way, he can grab the time and try to get these 3 sets of data this afternoon.

Then start to analyze the experiment as a whole, and adjust the current topic with the help of experimental data from other literature.

In addition, Chen Zhou has another reason for this arrangement.

That is Dr. Wu's preliminary processing of data, which is very informative.

This also provided Chen Zhou with more choices.

If there are 9 sets of raw data, then maybe this six-three will be Chen Zhou's six and Shen Jing's three.

Start with p-type doping.

Statistical analysis of the data is carried out on the factors affecting the preparation of boron-doped diamond, such as the doping concentration of boron and the crystal plane of the substrate.

Because the boron source selection of the 9 sets of data is B(CH3)3, so this experiment does not need to consider the influence of boron source.

Chen Zhou was completely immersed in the intense data analysis.

Perhaps because he knew the time was tight, Chen Zhou's hand movements were also much faster than usual.

Whether it is the speed of typing the keyboard, or taking a pen to record on the scratch paper.

Chen Zhou tried his best to catch up with the pace of the earth's rotation.

After the experimental data of p-type doping was settled, Chen Zhou began to process the data of n-type doping experiment.

N-type doping, that is, phosphorus doping.

In addition to considering the basic influencing factors such as the doping concentration of phosphorus, the crystal plane of the substrate, and the temperature, which are the same as p-type doping.

There is one more thing to consider.

That is the electron scattering mechanism of phosphorus-doped diamond, which also has an impact on the migration efficiency.

The electron scattering mechanism in diamond semiconductor is related to internal acoustic phonons, valley phonons, ionic impurities and neutral impurities.

At room temperature, when the doping concentration of phosphorus exceeds 1×10^18/cm, impurity scattering or defect state scattering plays a major role.

When the doping concentration of phosphorus is lower than this concentration, impurity ion scattering becomes acoustic phonon scattering.

Of course, this simple discrimination is not sufficient.

Because phosphorus doping itself also introduces other scattering.

Scattering due to internal stress due to bond length mismatches like phosphorus-carbon covalent bonds.

In addition, in different temperature ranges, the main scattering mechanism is also different.

At low temperature, acoustic phonon scattering is the main scattering mechanism.

At high temperature, electrons are affected by both acoustic phonon scattering and valley phonon scattering.

好在先前陈舟已经跟彭飞确认了磷的掺杂浓度是在4×10^15/cm~2×10^15/cm区间内依次选取的。

Based on the experimental data at hand, it is not difficult to judge the main factors of the scattering mechanism.

After the n-type doped data ends, the co-doped data remains.

Co-doping is also n-type doping. After gaining experience once, Chen Zhou handled it much more easily.

Soon, the experimental data processing of co-doping was completed.

In this way, a set of experimental data comes to an end.

Chen Zhou glanced at the time, it took nearly two hours.

It's acceptable, after all, the first time, it will always be slower.

Next, it should be soon.

Without stopping, Chen Zhou began to process and analyze the experimental data of the second and third groups.

Once a plan is made, the necessity of the plan cannot be proved until it is completed.

Time passed quietly between Chen Zhou's fingers.

The ever-growing documents on the computer, as well as the stacked pieces of draft paper, are showing the results of Chen Zhou's work.

At six o'clock in the afternoon, Chen Zhou typed the last paragraph on the computer.

As planned, all three sets of data were processed in one afternoon.

Chen Zhou saved the information and was about to get up to check on Shen Jing's progress.

By the way, move your muscles and bones again.

Sitting in front of the computer and working all afternoon, Chen Zhou felt a little stiff all over his body.

Fortunately, Chen Zhou is used to this kind of work mode, so he doesn't feel too tired.

However, he secretly sighed: "Thanks to the reminder from the system, you must develop good living habits, otherwise, if you don't keep your body in place for a long time, you will have problems."

Just as Chen Zhou was walking towards Shen Jing, Peng Fei and Pan Shiyan came to their small office.

The moment he saw Peng Fei, Chen Zhou suddenly thought of what he said earlier.
