Chapter 428: The rest is fine

Seeing Yang Xiaoman operating the equipment proficiently, Xu Mang felt that bringing Xiaoman over this time was almost one of the wisest decisions he had made in his life, but there was a reason why Xiaoman was proficient in the past six months. She is skilled at manipulating the gears!
Speaking of myself, I am not up for it, and it is a great shame to be grasped by a short flat and flat!
"Ugh!"
"The three stacked data of aaa, aba, and ab have come out. Come and take a look for yourself." Yang Xiaoman greeted Xu Mang on the side, staring at him with both eyes, and he couldn't help but burst out. Hongxia of the formation said shyly: "What's the matter?"
"It's nothing"
Xu Mang returned to his senses and walked to Xiao Man in embarrassment. He didn't dare to say what he was thinking about. He would definitely be beaten by Fat.
"Is this the spatial distribution map of Fermi's intensity points from 01 to 05 eV?" Xu Mang asked curiously, "How come it seems that there is no difference? Did you make a mistake?"
"impossible!"
"I'm serious." Yang Xiaoman said firmly with a face: "If I make a mistake, I let you hit my at night, don't you think about it in your dreams?"
"Go away!"
"I want to check it!" Xu Mang heard Yang Xiaoman's words and drove her off the chair on the spot. He stared at the display screen and checked the data from start to finish. The expression on his face was a little weird and excited. There was a trace of expectation and fear in it, and there was also faint fear mixed in.
Yang Xiaoman: (#￣～￣#)
Finally admitted!
Look at my old lady, I can't kill you at night!
After checking for almost ten minutes, Xu Mang did not find any wrong place. At this time, he had to accept this reality and turned his head cautiously. Seeing a strange smile on Xiaoman’s face, he knew that he would not sleep tonight again. night of.
Ugh
Life is hard!
"how?"
"Look at your disappointed look." Yang Xiaoman said disdainfully: "Do you still question me in the future?"
"Ha ha"
"Look at what you said." Xu Mang smiled awkwardly: "Even if I question the heavens and the earth, and then question the air in the middle, I don't dare to question the Queen, the results of your experiments make me very satisfied."
"Humph!" Yang Xiaoman snorted coldly, and hurriedly asked: "What should I do next?"
Xu Mang thought for a while and said seriously: "The data is fitted to get the transition parameters of the energy band, and then it is almost done because the next step is the calculation problem. When we calculate it together, I suspect that the structure of aaa may be generated. Superconductivity."
"Let me do the fitting calculation for you." Yang Xiaoman said calmly.
"Do you know how to fit?" Xu Mang asked, looking at Xiaoman.
"Fitting is to connect a series of points on the plane with a smooth curve." Yang Xiaoman said: "The simpler is a smooth curve to connect the data. Mother, I am studying economics, and there is simulation in it. A statistic of the degree of goodness that measures the gap between the expected value of an economic model and the actual value obtained in reality.
Words fall,
Yang Xiaoman said: "Don't forget that I am the number one in the world math competition!"
Seeing Xiaoman's serious expression, Xu Mang asked curiously: "Xiaoman, do you really plan to enter the financial circle? Take over the business in the house?"
"Ok"
"Originally, my mother wanted you to take over, but you have chosen the path of scientific research, so I can only take over." Yang Xiaoman pouted and said silently: "I can't really let my dad do it until 70 Eighty years old, right?"
Xu Mang grabbed Xiaoman's hand and said softly: "I will be by your side forever!"
"Ok"
after that,
Began to calculate intensely,
This work is relatively boring. The two of them are reminiscing about the interesting things in the past while performing fitting calculations. It takes about half an hour. The calculation results come out. What makes Xu Mang desperate is that there is only one stacking method that may produce super guide.
In the ab-style stacking, the dispersion of electrons at the Fermi energy of graphene is very small, resulting in a greatly increased density of states at the Fermi energy, creating a possibility for superconductivity, but this possibility is too great. Mysterious.
This result surprised Xu Mang. At first he thought it was the aaa stacking method, but it turned out to be his most unsightly stacking method.
But there are also unexpected gains,
In the case of an external vertical electric field, the Fermi energy will open the energy gap and the size of the energy gap can be adjusted by the electric field strength.
"what happened?"
"Look at your dumbfounded look." Yang Xiaoman didn't know what happened to Xu Mang, and hurriedly asked: "Is it useless to find out?"
"Ok!"
"It's completely different from what I expected." Xu Mang frowned, flipping through the data, and said painfully: "The data shows that the stacking method that is most likely to produce superconductivity is the most unsightly one before me."
"Then accept the facts." Yang Xiaoman said disapprovingly: "It's not a big deal."
Xu Mang sighed and said helplessly: "If this is the case, it will be fine. The problem is the stacking method of ab, but there is the possibility of its superconductivity. However, I just discovered that this is impossible. Anyway, I failed."
Yang Xiaoman looked at Xu Mang's disappointed expression and decadent state. He didn't know what to do for a while, so he could only silently comfort him: "Don't worry, we will succeed."
"Ok"
Xu Mang is now very unconvinced. He decided to start all over again and start from the most basic research. The first thing is to collect relevant papers, not to mention that Xu Mang has found relevant information in a certain paper.
It is about the electronic regulation of graphene molar superlattices.
but
There are not many data in this paper, most of which are predictions, but it gave Xu Mang a whole new inspiration.
"Little Man!"
"Help me figure this out." Xu Mang pointed to a large calculation process he had written on paper, and said solemnly: "I have to do other things."
"Ok!"
"I will finish it." Although the calculation process of this blockbuster made Yang Xiaoman feel a headache, she still gritted her teeth. At this time, willfulness is not a good thing, after all, this is related to the reputation of her fiance.
While Xiaoman was working hard to calculate, Xu Mang set out to search for papers on graphene and boron nitride.
soon,
Xu Mang found an article that an optical absorption peak was observed in the graphene molar superlattice, which corresponds to the electronic transition near the Dirac point of the superlattice.
The graphene state of this content is exactly the same as the aaa stacking method, but the data is completely different.
understood!
finally understood!
Xu Mang suddenly realized that there was no error in his guess, but the set of data he gave was wrong. Now he waits for Xiaoman to calculate the result. If the result is similar to what he imagined, then there is no problem.
so close,
It was almost a tragedy.
At this time, Xu Mang had a feeling of being left behind, almost not autistic.
However, Xu Mang was not idle, and began to estimate the aaa stacking method of three-layer graphene. In his estimation, the superconductivity of three-layer graphene requires another material to be stacked. This material is boron nitride. .
And his basis is from the paper just now, when graphene is on a boron nitride substrate, the influence of the electronic state optical transition will decrease as the Fermi level in the graphene increases.
4:30 in the afternoon,
Yang Xiaoman finally solved the task Xu Mang gave her. When he handed the paper with the calculation process to Xu Mang's hand, it didn't take long for Xu Mang to jump up excitedly, holding Xiaoman as a kiss. .
(￣▽￣)e￣)
(￣3(￣▽￣)
(￣3)(e￣)
This made Xiaoman happy. She rarely had such a passive experience, and basically forced him to do it by herself.
"Success!"
"Xiao Man!" Xu Mang hugged her tightly and said with a happy face: "The two of us have pushed graphene to a whole new level!"
in fact,
Yang Xiaoman doesn't take these seriously, she is still immersed in the happiness just now, unable to extricate herself for a long time.
A canteen in Jiang Da,
Xu Mang and Yang Xiaoman were having a meal. Among them, countless girls found Xu Mang with a shy expression and asked to take a photo with him. Xu Mang would never refuse this request, but until a green tea appeared, Kicked over the vinegar jar that was originally filled with vinegar.
"Professor Xu!"
"Why are you here?" A good-looking girl found Xu Mang's figure and said obsessively: "Professor Xu, I am a fan of yours. I especially like you. Since your live broadcast, I am completely fanned by you."
Humph!
Fans?
I'm still a noodle, mother!
Looking at the gorgeous girl in front of him, Yang Xiaoman felt that this woman did not look like a good person. Judging from her quite mature breath, this person must have a special purpose. Maybe she wants to use Xu Mang to make herself a one. Internet celebrity.
Be vigilant!
Be vigilant!
"younger sister?"
"Take a photo with Professor Xu for me, thank you." The girl handed the phone to Xiaoman, and then she was next to Xu Mang, her head turned to Xu Mang's side.
Yang Xiaoman almost didn't explode on the spot, but bearing in mind his cousin's iron rules, he didn't get angry and took a picture silently.
"Dear?"
"Are you full?" Yang Xiaoman said blankly: "If you are not full, I'll make another copy for you."
"Okay!"
Yang Xiaoman: (￣︿￣)
How big you are!
Mother, I'm warning you to leave!
but,
In the end, Xiaoman went to give Xu Mang a meal, but due to the large number of people, it may take a long time.
And this just gave the girl next to Xu Mang a chance to pry the corner.
"Professor Xu?"
"Is that your girlfriend just now?" The girl asked curiously, "It seems that she is not good in all aspects of her figure."
""
"Excuse me, please lean aside." Xu Mang frowned and said, "I will be misunderstood later."
The girl moved to the side obediently, and said affectionately: "Professor Xu, you are so perfect, why can't I meet such a nice person as you?"
Faced with this problem,
Xu Mang thought about it seriously, and said with a serious face: "Maybe your life is bad!"
I
This
Hearing Xu Mang's words, the girl didn't know how to answer the conversation for a while.
Is it a straight man?
"I say"
"The pictures were taken, and the chat was over. You should almost leave, right?" Xu Mang said helplessly: "Your perfume is poisonous, and I almost smell it."
With a hint of resentment,
This unruly girl left Xu Mang and happened to meet Yang Xiaoman who came back with food.
Contrast it with ~EbookFREE.me~ The girl with a bad heart really can't understand why Professor Xu Mang Xu would find such a person to be his girlfriend. Apart from having a pretty face, she is better than her in any other place.
"Ugh?"
"Why did the girl who haunted you stare at me?" Yang Xiaoman handed the food he had just called to Xu Mang and asked strangely.
"do not know."
Xu Mang was frantically grilling rice, his mouth filled with oil.
"Idiot?"
"When are we going back?" Yang Xiaoman sat opposite him and asked curiously.
"tomorrow morning."
"There is nothing wrong with the rest." Xu Mang said proudly: "We black wind and two evil spirits will once again shock the world!" Remember the website of this site, www. biquxu. Com, easy to read next time, or enter "" on Baidu to enter this site
