"Let's do the math first, don't rush to ask for the result, but ask for the whole ......"

This is Chen Zhou's current thinking, he is not going towards the only result as soon as he gets the data, but starting from many aspects.

Since the problem of diodes is so complicated, then strip it away and break it one by one.

On Chen Zhou's scratch paper, the famous Mott-Gurney law is written.

This is an extremely important formula for space charge limiting currents.

Space charge refers to the remaining charge that is present in a local area inside a semiconductor.

The space charge effect refers to the fact that the concentration of carriers in the space charge region may exceed or be less than its equilibrium carrier concentration under external actions such as bias pressure.

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

Although the diode is not a semiconductor, it is a single-conductive electronic component made of semiconductor materials, which belongs to the device of semiconductor materials, so there will be a charge effect between classes.

"The ...... of the Child-Langmuir Law"

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

Chen Zhou remembers that when the equivalent explosive electron emission boundary was used at the cathode metal boundary, when the field strength of the cathode surface exceeded the breakdown threshold, the cathode surface would quickly cover the plasma.

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

Of course, this is an ideal simulated situation, and it certainly won't be the case in the real world.

However, this does not prevent Chen Zhou from using the Zeld-Langmuir law based on reasonable assumptions.

As the minutes ticked by, the sky outside the library had darkened.

Putting down the pen in his hand, Chen Zhou sorted out the scratch paper that he had written a little messy.

Anyway, it's not too difficult, but it's just too cumbersome.

Looking at the time, it was already half past six.

At this time, Chen Zhou's stomach also protested in a timely manner.

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

It's just that it's a bit of a drag today.

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

Yang Yiyi was still engrossed in sorting out the information.

Unlike others, Yang Yiyi simply analyzed his thoughts on the parameters of the reverse extrapolation equipment while sorting out the data, and wrote them down at the back of each experimental data.

After Chen Zhou saw these contents, he thought about it, and he turned his head to look at his computer again, opening a new word page.

Chen Zhou briefly described his whole idea of retrogression, including the physical knowledge and theoretical formulas that might be used in it.

After doing this, he saved the document and sent it to Yang Yiyi.

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

Yang Yiyi nodded and accepted the document sent by Chen Zhou.

She didn't just click on it, but continued to finish the rest of the work at hand.

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

It's really tiring to work at the desk for a long time.

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

Ah, it's still beautiful......

Yang Yiyi said softly: "Let's go." ”

Chen Zhou: "Uh...... Walk...... Well, let's go, let's eat and ......."

Yang Yiyi frowned slightly, and then laughed softly, and secretly said in her heart: "Idiot!"

After dinner, Chen Zhou and Yang Yiyi walked hand in hand on the campus of Yan University.

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

That tone is very envious!

Of course, some people envy why this big guy has a girlfriend, and he can prove the hail conjecture?

And he is nothing......

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

After all, Yan Da, who has been a man of the wind for so long, still has this anti-interference ability.

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

At 8 o'clock in the evening, Chen Zhou and Yang Yiyi did not go to the library again, but chose the study room.

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

In fact, what they didn't know was that the place where the two of them often sat in the library had been silently marked by their classmates in their hearts.

Even if they don't, few will take their place.

Everyone assumed that it was the exclusive place for the two of them.

8 o'clock to 10:30 o'clock.

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

Although the final result of the reverse deduction is still far away, the two of them have gained a lot from the process of doing so.

Previous experimental studies are all coming in the right way.

This will be a positive and negative comparison, which deepens the understanding of the two of them about particle accelerator experiments.

sent Yang Yiyi downstairs to the girls' dormitory, and Chen Zhou returned to his dormitory.

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

However, before Chen Zhou could speak, the dormitory manager aunt automatically stopped locking the door.

The aunt greeted Chen Zhou with a smile and said, "The great mathematician is studying so late again? Hurry, come in." ”

Chen Zhou hurriedly walked into the dormitory building: "Auntie, thank you, you are so good." ”

The dormitory manager said with a smile: "Thank you, can Auntie still shut you out?" Auntie knows that you study mathematics hard, and it is not a big deal to leave a door." ”

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

Before he could go far, Chen Zhou heard a voice behind him.

"Auntie, open your grace and let me in. I'm a little late, I promise not next time!"

"Do you want to have a next time? No, the rules of the dormitory are the rules, you write a review first. ”

"Auntie, you are good, I really don't dare. And besides, I just saw that somebody didn't go in too? You didn't even ask him to write it. ”

Hearing this, the dormitory manager immediately said: "That's different, Chen Zhou is busy studying mathematical problems, and when he studies it, he definitely doesn't know the time, and he can't be blamed for it." If I don't let him in, if I don't get a good rest and delay him from solving a world-class problem, then I won't be a sinner?"

Only then did this classmate know that it was Chen Zhou who was put in by the dormitory manager before, well, the treatment of the big guy was really different.

However, it's the same with myself, this is entangled with my girlfriend, isn't it just immersed in it, and it's easy to forget the time......

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

In desperation, he had to use the hard work.

After returning to the dormitory and washing up, Chen Zhou, who was lying on the bed, remembered that he seemed to have forgotten something.

I opened my phone and took a look, so let's forget it and call the professor back tomorrow morning.

Well, the world of backward deduction is so wonderful, I almost forgot to eat when I studied it, so it should be understandable that Professor Wu forgot to call back......

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

In the dream, he came to the library again.

Yang Yiyi is also in a familiar position.

Yang Yiyi raised her head and looked at each other.

The two looked at each other and smiled.

Then, the formula is flying.

And the countless experimental data, and the shapes of all kinds of shapes.

When Chen Zhou stretched out his hand to touch it, he found that he suddenly touched Yang Yiyi's face.

Yang Yiyi's face was flushed with a hint of blush, and her eyes were warm and affectionate when she looked at Chen Zhou.

Immediately, Yang Yiyi slowly closed her eyes.

Chen Zhou's attention also shifted to the seductive red lips......
