Volume 1: Student Life Chapter 234: The reverse world is really amazing
"Let's calculate everything first. Don't rush for the result, but ask for the whole face..."
This is Chen Zhou’s current idea. He does not go for a single result as soon as he gets the data, but starts from multiple aspects.
Since the diode problem is so complicated, let's peel it off and break it down one by one.
Written on Chen Zhou's draft paper is the famous Mott-Gurney Law.
This is an extremely important formula for space charge limited current.
Space charge refers to the residual charge that exists in a local area inside a semiconductor.
The space charge effect refers to the fact that under external influences such as bias, the concentration of carriers in the space charge region may exceed or be less than its equilibrium carrier concentration.
The space charge effect is a problem encountered in semiconductor materials and devices, especially at high currents, where space charge may play a decisive role.
Although the diode is not a semiconductor, it is a unidirectional conductive electronic component made of semiconductor material. It is a device of semiconductor material, so there will be a charge effect.
"As for the Zeld-Langmuir law..."
Chen Zhou thought for a while and wrote down the formula of this law.
Chen Zhou remembers that when an equivalent explosive electron emission boundary is used at the cathode metal boundary, when the field strength on the cathode surface exceeds the breakdown threshold, the cathode surface will be quickly covered with plasma.
At this time, the normal electric field E on the cathode surface remains zero, and the current value of the electrons emitted by the cathode satisfies the Zeld-Langmuir law.
Of course, this is an ideal simulation, and the real situation will definitely not be like this.
But this does not prevent Chen Zhou from using the Zeld-Langmuir law based on reasonable assumptions.
Time passed by minute by minute, and the sky outside the library had darkened.
Putting down the pen in his hand, Chen Zhou tidied up his messy draft paper.
How should I put it, this thing isn't too difficult, but it's just too troublesome.
I looked at the time and it was already half past six.
At this time, Chen Zhou's stomach also protested in time.
Since they developed good living habits, he and Yang Yiyi have a very regular diet.
It's just that I was a little delayed today.
Tilting his head slightly, Chen Zhou looked at Yang Yiyi beside him.
Yang Yiyi was still concentrating on organizing the information.
Unlike others, Yang Yiyi, while organizing the data, also made a simple analysis of her ideas on the reverse engineering equipment parameters and wrote them behind each type of experimental data.
After seeing these contents, Chen Zhou thought about it, then turned back to his computer and opened a new Word page.
Chen Zhou briefly described his entire idea about reverse reasoning, including the physical knowledge and theoretical formulas that might be used.
After doing all this, he saved the file and sent it to Yang Yiyi.
"Yiyi, it will be faster if we calculate together."
Yang Yiyi nodded and accepted the file sent by Chen Zhou.
She didn't click it directly, but continued to complete 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 stretching, Chen Zhou couldn't help but think of this time last year.
Yeah, still beautiful...
Yang Yiyi said softly, "Let's go."
Chen Zhou: "Uh... let's go... um, let's go and have dinner..."
Yang Yiyi frowned slightly, then laughed softly, and said in her heart: "Idiot!"
After dinner, Chen Zhou and Yang Yiyi walked hand in hand on the campus of Yanda University.
From time to time, I can hear people around me talking about academic conferences.
That tone is so envious!
Of course, some people are envious of why this big guy has a girlfriend and can also prove the hail conjecture?
And I am nothing...
Chen Zhou and Yang Yiyi could occasionally hear these people talking, but they were used to it.
After all, as a prominent figure in Yan University for such a long time, he still has some ability to resist interference.
As long as it doesn’t completely affect the normal lives of the two of them like it did some time ago.
At 8 o'clock in the evening, Chen Zhou and Yang Yiyi did not go to the library, but chose the study room.
If they go to the library again this time, they are afraid that they won’t be able to get a seat.
What they didn’t know was that the seats where the two of them often sat in the library had been silently marked by their classmates.
Even if they don't go, few people will go to reserve a seat.
Everyone assumed that it was the exclusive seat for the two of them.
8:00 to 10:30.
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 deduction is still far from being achieved, the two have gained a lot from the process.
Previous experimental studies were all conducted in a positive manner.
This positive and negative comparison deepened the two people's understanding of particle accelerator experiments.
Only after sending Yang Yiyi to the downstairs of the girls’ dormitory did Chen Zhou return to his own dormitory.
When he arrived downstairs of the dormitory, he saw the dormitory manager preparing to close the door.
However, before Chen Zhou could say anything, the dormitory manager automatically stopped locking the door.
The aunt greeted Chen Zhou with a smile, "Are you a great mathematician working so late again? Come in quickly."
Chen Zhou quickly walked into the dormitory building: "Auntie, thank you, you are so kind."
The dorm auntie smiled and said, "Why thank you? Can I still lock you out? I know you study mathematics very hard, so leaving the door open is not a big deal."
Chen Zhou smiled, thanked him again, and walked towards the dormitory.
Before he had walked far, Chen Zhou heard a voice behind him.
"Auntie, please be merciful and let me in. I was just a little late, I promise I won't do it again next time!"
"Do you want to do it again next time? No, the dormitory rules are the rules. You need to write a letter of apology first."
"Auntie, please be kind. I really don't dare to do it anymore. Besides, didn't I see someone go in just now? You didn't even let him write it."
Hearing this, the dormitory manager immediately said, "That's different. Chen Zhou is busy studying math problems. Once he starts studying, he definitely loses track of time. It's not his fault. If I don't let him in, and he doesn't get enough rest, delaying his solving of world-class problems, wouldn't I be a sinner?"
The classmate then realized that the person who had been let in by the dormitory manager was Chen Zhou. Well, the treatment of the big guys is indeed different.
But it's the same for me. When I'm with my girlfriend, I get so immersed in it that it's easy to forget the time...
Of course, he still didn't dare say this.
In desperation, he had to resort to both soft and hard tactics.
After returning to the dormitory and washing up, Chen Zhou, lying on the bed, suddenly remembered that he seemed to have forgotten something.
I opened my phone and took a look. Forget it. I'll call the professor back early tomorrow morning.
Well, the world of reverse engineering is so wonderful. I almost forgot to eat while studying it . So, it’s understandable that I forgot to return Professor Wu’s call…
Thinking of this, Chen Zhou soon fell asleep.
In his dream, he came to the library again.
Yang Yiyi was also in a familiar position.
Yang Yiyi looked up and their eyes met.
The two looked at each other and smiled.
Then, formulas were flying all over the sky.
There are also countless experimental data and graphs of various shapes.
When Chen Zhou reached out to touch her, he suddenly found that he touched Yang Yiyi's face.
Yang Yiyi's face was slightly flushed and she looked at Chen Zhou with tender eyes.
Immediately, Yang Yiyi slowly closed her eyes.
Chen Zhou's attention also shifted to those tempting red lips...
