Chapter 234 The Reversed World Is Really Wonderful
"Let's do the math first, don't rush for the result, but ask for the whole face..."

This is Chen Zhou's current thinking. He didn't go towards the only result as soon as he got the data, but started from multiple aspects.

Since the problem of diodes is so complicated, let's peel it off and break it down one by one.

On Chen Zhou's draft paper, the famous Mott-Gurney law was written.

This is an extremely important formula for space charge limited current.

Space charge refers to residual charges that exist in localized regions inside a semiconductor.

The space charge effect refers to that under external effects such as bias voltage, in the space charge region, the carrier concentration may exceed or be less than its equilibrium carrier concentration.

Space charge effect is a problem encountered in semiconductor materials and devices, especially at high currents, space charge may play a decisive role.

Although a diode is not a semiconductor, it is a one-way conductive electronic component made of semiconductor materials. It is a device of semiconductor materials, so there will be an inter-class charge effect.

"In terms of the Zeld-Langmuir law..."

Chen Zhou thought for a while, and wrote down the formula of this law.

Chen Zhou remembers that when the equivalent explosive electron emission boundary is used on the cathode metal boundary, when the cathode surface field strength exceeds the breakdown threshold, the cathode surface will be quickly covered with plasma.

At this time, the normal electric field E on the surface of the cathode is maintained at zero, and the current value of electrons emitted by the cathode satisfies the Zeld-Langmuir law.

Of course, this is an ideal simulated situation, which is certainly not the case in real situations.

But this does not prevent Chen Zhou from using the Zeilder-Langmuir law based on reasonable assumptions.

Time passed by like this, and the sky outside the library had already darkened.

Putting down the pen in his hand, Chen Zhou sorted out the messy draft paper he had written.

How should I put it, the difficulty of this thing is not too great, but it is too troublesome.

Looking at the time, it was already 6:[-].

At this time, Chen Zhou's stomach also made a timely protest.

Since he developed good living habits, he and Yang Yiyi's diet is still very regular.

It's just that today is a bit late.

Turning his head slightly, Chen Zhou looked at Yang Yiyi beside him.

Yang Yiyi was still concentrating on sorting out the materials.

Different from others, while sorting out the data, Yang Yiyi also briefly analyzed her own thoughts on the parameters of the reverse derivation equipment, and wrote it down behind each type of experimental data.

After seeing these contents, Chen Zhou thought for a while, then turned his head to look at his computer again, and opened a new word page.

Chen Zhou gave a brief description of his whole idea about inversion, including the physical knowledge and theoretical formulas that may be used in it.

After finishing all this, he saved the file and sent it to Yang Yiyi.

"Yiyi, let's calculate together, it will be faster."

Yang Yiyi nodded and accepted the document from Chen Zhou.

She didn't click on it directly, but continued to finish the remaining work at hand.

After confirming that the information was kept, Yang Yiyi stretched.

Working at a desk for a long time is really tiring.

Looking at Yang Yiyi who was stretching, Chen Zhou unconsciously thought of this time last year.

Yeah, it's still beautiful...

Yang Yiyi said softly, "Let's go."

Chen Zhou: "Uh... let's go... well, let's go, let's eat..."

Yang Yiyi frowned slightly, then laughed softly, and said inwardly, "Idiot!"

After dinner was settled, Chen Zhou and Yang Yiyi walked around the campus of Yanda holding hands.

From time to time, I can hear people around me talking about academic conferences.

That tone is very envious!
Of course, what some people are envious of is why this boss has a girlfriend and can prove Hail's conjecture?
But I am nothing...

Chen Zhou and Yang Yiyi could occasionally hear these people talking, but they were used to it.

After all, he has been a man of influence in Yanda for so long, so he still has the ability to resist interference.

As long as it doesn't completely affect the normal life of the two of them like it did some time ago.

At 8 o'clock in the evening, Chen Zhou and Yang Yiyi chose the study room instead of going to the library.

I will go to the library again, and the two of them are afraid that they will not be able to occupy a seat.

In fact, what they don't know is that the places where the two of them often sit in the library have been silently marked by the students in their hearts.

Even if they don't go, few people will take a seat.

Everyone defaulted that it was the exclusive position of the two of them.

8:10 to [-]:[-].

For two and a half hours, Chen Zhou and Yang Yiyi continued to be completely immersed in the ocean of data.

Although the final result of the reverse push is still far away, the various things in the process have already benefited the two of them a lot.

The previous experimental research is all right.

This will be a positive and negative comparison, which will deepen the two people's understanding of the particle accelerator experiment.

After sending Yang Yiyi downstairs to the girls' dormitory, Chen Zhou returned to his own dormitory.

When he got downstairs in the dormitory, he saw the dormitory auntie preparing to close the door.

However, before Chen Zhou could make a sound, the housekeeper aunt automatically stopped locking the door.

The aunt greeted Chen Zhou with a smile: "The great mathematician has been studying so late again? Come in quickly."

Chen Zhou hurried into the dormitory: "Auntie, thank you, you are so kind."

The dormitory auntie smiled and said, "Thank you, can auntie shut you out? Auntie knows that you study mathematics hard, so it's not a big deal to keep the door open."

Chen Zhou smiled, thanked him again, and walked towards the dormitory.

Before he had gone far, Chen Zhou heard a voice behind him.

"Auntie, please be kind and let me in. I'm a little late, and I promise I won't do it next time!"

"Do you still want to have a next time? No, the rules of the dormitory are the rules. You should write a self-criticism first."

"Auntie, please do me a favor. I really don't dare. Besides, didn't I see someone go in too? You didn't let him write."

Hearing this, the dormitory aunt immediately said: "That's not the same. Chen Zhou is busy studying mathematics problems. When he starts to study, he must not know the time. It can't be his fault. If I don't let him in, in case If I haven't had a good rest and delayed him from solving world-class problems, then I won't be a sinner?"

Only then did the classmate know that it was Chen Zhou who was put in by the dormitory aunt earlier. Well, the treatment of the boss is really different.

But, it's the same for me, once I'm in love with my girlfriend, I'll be immersed in it, and it's easy to forget the time...

Of course, he still didn't dare to say that.

In desperation, he had no choice but to resort to hard work.

After returning to the dormitory and washing up, Chen Zhou, who was lying on the bed, remembered something, as if he had forgotten something.

Turn on the phone and take a look, forget it, and call the professor back tomorrow morning.

Well, the world of reverse derivation is really wonderful, and I almost forgot to eat during the research, so it should be understandable for Professor Wu to forget to call back...

Chen Zhou, who was thinking like this, soon fell asleep.

In the dream, he came to the library again.

Yang Yiyi was also in a familiar position.

Yang Yiyi raised her head, her eyes met.

The two smiled at each other.

Afterwards, the sky filled with formulas were flying.

There are also countless experimental data and graphics of various shapes.

When Chen Zhou reached out to touch, he found that he suddenly touched Yang Yiyi's face.

Yang Yiyi's face was flushed, and she looked at Chen Zhou with tender eyes.

Immediately, Yang Yiyi slowly closed her eyes.

Chen Zhou's attention was also shifted to those alluring red lips...
