Chapter 169 The Truth is in My Hands Lu Shan didn't know how the people in the materials and chemistry team evaluated him. He didn't have the leisure to guess. Even if he knew, he didn't have the energy to think about it. There were too many things to do. During this period, Lu Shan frequently went in and out of the library and laboratory, which was basically equivalent to living outside. If he studied too late, he would simply rest in a hotel outside the school. After all, it was far from the company, and he was afraid of disturbing others if he went back to the dormitory. There are definitely night owls in the dorm, but there are definitely people who are asleep. Long-term intensive research made Lu Shan's overall model more perfect. Poincare and Turing cooperated more and more tacitly, and gradually tolerated each other's weirdness. However, Poincaré was still somewhat afraid of Turing, because this American had the wrong inclinations and he felt intimidated. Lu Shan was rarely bothered by matters at the company. On the day of the dividend distribution, Wang Ping contacted Lu Shan to come over and sign. After signing, Pete received dividends. Peter was shocked. According to the cash dividends he received, Lu Shan's dividends for the first quarter were about 500,000. In other words, the company could earn 6 million a year! This was just the current low point. If Lu Shan could really succeed in his layout, his profitability would definitely be very strong. IDG acquired shares in March and paid dividends within just one month. Lu Shan is a very honest person and this company has a bright future.
IDG has invested in many companies, but none of them can make a profit from their business and they have been raising funds all the time. Investors never expect dividends from a company's operations; their goal is the stock market! As long as it is listed, you can find someone to take over and cash out. The stock market is a murky place, and both short selling and buying can make profits. Investors will also contact large speculators to set up a scheme, and in the end, only retail investors or smaller speculators are the ones who get hurt. After getting the money, Lu Shan immediately established Bansi Materials Technology Co., Ltd. The reason for doing this is that during his research on topological semimetals, Lu Shan discovered that the performance of many materials exceeds that of existing semiconductor materials and can change the direction of future semiconductor development. These materials performed extremely well in the experiment and were highly consistent with their own experimental models. The only problem was that there were too few things in the laboratory, not enough for their own research. If they wanted to do research, they had to do it themselves and then put them in the laboratory for experiments. Going to do experiments frequently allowed Lu Shan to find a like-minded partner, Zhang Lingxi, a senior student in the School of Materials Science and Engineering. She had black-framed glasses and a baby face, but her figure was amazing. She looked 1 meters tall, but her actual height was 67 meters. The night they met Zhang Lingxi, they were both really scared. Lu Shan walked into the laboratory on his own, and Zhang Lingxi had just taken off his coat and was changing into lab clothes. When he heard someone behind him, he turned around immediately and screamed in fright. Lu Shan only then noticed someone. He was busy putting down his bag and looking through some documents, and didn't notice there was someone behind him at all. "Um, if I say I didn't see anything, would you believe it..." After hesitating for a moment, Lu Shan looked at Zhang Lingxi, whose face was flushed and speechless, and decided to speak first. "Lu Shan? What are you doing here?" Zhang Lingxi recognized Lu Shan. She was already in the materials chemistry team and could only serve as an assistant, doing some minor experiments. The team was full of doctoral students, so how could she, an undergraduate, have a chance to speak? So Lu Shan didn't notice this person at the academic exchange meeting. To be honest, Lu Shan was also selectively blind. He had never noticed such a beautiful woman here... When Lu Shan heard Zhang Lingxi's question, he answered while operating the equipment: "Use the lab for a while and find some data. They use it during the day, and I'll come over at night to see if there's any idle equipment and do whatever I can." Zhang Lingxi walked to Lu Shan and explained softly, "I'm cleaning the lab here, and by the way...thinking about the experiment." "Oh!" Lu Shan answered very perfunctorily, and Zhang Lingxi didn't know how to respond. After a moment of awkward silence, Zhang Lingxi left on his own. In the following days, Zhang Lingxi and Lu Shan met three times, and they communicated more and more each time.
"How do you understand the large transverse thermoelectric effect of topological semimetals?" "I think that in topological electronic materials, the transverse thermoelectric effect where the temperature difference and voltage are perpendicular to each other is much larger than we previously imagined. The application of thermoelectric materials is not necessarily limited to the longitudinal direction where the temperature difference and voltage are parallel." "If we use the lateral thermoelectric effect, we can cleverly 'bypass' the above difficulties of the traditional thermoelectric effect and transform them into the unique advantages of the lateral thermoelectric effect." "That's a good idea. The lateral thermoelectric effect no longer distinguishes between electrons and holes. The effects of the two are equivalent and superimposed on each other. Charge-hole compensation leads to an enhanced lateral thermoelectric effect. In practical applications, the series structure of n-type and p-type materials is no longer required." "In addition, since the heat flow and electric current flow in the perpendicular direction, the restrictions of the Wiedemann-Franz law are lifted, and we can optimize the electrical and thermal conductances relatively independently." "More importantly, the Berry curvature caused by the band structure of topological materials can produce additional anomalous transverse thermoelectric effects, the size of which can be adjusted by changing the Fermi energy. Your research is quite solid." Lu Shan looked at this senior sister seriously for the first time. If they talked about other things, Lu Shan had no time to pay attention. If they talked about research, Lu Shan was very happy. Sometimes waiting for research is too boring, and talking about research is a good way to pass the time. Tonight, I was still working on single crystal preparation to verify my ideas, so the process was particularly long and I would definitely stay up all night. "The precursor of FeSn2 single crystal is prepared by flux method. In a glove box filled with argon, high-purity Fe powder (purity of , Aladdin) and Sn powder (, Aladdin) are mixed at a molar ratio of n(Fe) : n(Sn) = 1:9, and evenly ground in an agate grinder for 2 hours before being put into a quartz tube. The quartz tube is then simply sealed and taken out of the glove box. It is quickly placed in a vacuum packaging system and the tube is evacuated and sealed. It is then placed in a box-type high-temperature furnace for sintering. It is slowly heated from room temperature to 773K and kept warm for 4 weeks. It is then slowly cooled to 545K at a rate of 2K/h (to precipitate FeSn2 single crystals with a smaller volume). The quartz tube is then inverted in a centrifuge and rotated rapidly to remove excess tin..." Lu Shan muttered to himself, his hands busy. Zhang Lingxi asked questions during the free time and took notes continuously. "I've always thought your idea was right, and the experiments you've done these days have made me even more certain of this. Unfortunately, it seems like the people in the team are not willing to believe you. It's a pity that I have no say..." Zhang Lingxi looked regretful, as he had little influence. Lu Shan didn't care: "It's okay, it may be my fault. Many things seem to be true, but no one can say for sure before the results come out." "I think yours is right!" Zhang Lingxi was very firm. "Thank you for your trust." In this way, Zhang Lingxi became Lu Shan's assistant in doing experiments at night. Following Lu Shan, she learned a lot of knowledge. In universities, graduate students and doctoral students are actually employees of their supervisors before graduation, helping with projects and receiving low subsidies. Many supervisors do not have time to provide guidance and just give projects to students to study on their own. Zhang Lingxi is very afraid that this will happen to him. Now he learns more from Lu Shan so that he will feel more at ease when studying for a master's degree in the future. After finishing the experiment in the evening, it was usually around two o'clock. No matter how cold Lu Shan was, he couldn't bear to watch Zhang Lingxi go back to the dormitory alone. On the one hand, it is unsafe, but on the other hand, he is helping me for free, so I should give him a gift. That night, the two of them walked slowly on the way back to the girls' dormitory. Everything around them was so quiet. The street lamps were well lit, but were obscured by the moonlight. The light of the street lamps was shrouded in moonlight, looking gentle and hazy. The atmosphere suddenly became ambiguous, and Zhang Lingxi was a little nervous. She was not sent back by the opposite sex at this point. Suddenly, there was a sound of people talking in the distance, as if several people were coming towards them. Zhang Lingxi was a little nervous and subconsciously moved closer to Lu Shan and grabbed Lu Shan's arm. The touch felt complicated and comfortable. "All the weight is on me!" Lu Shan wanted to push her away, but failed, so he gave up. "Eh? It's Lu Shan!" The person called out Lu Shan's name. It turned out that Gao Chuan and his group had just returned from having supper and met Lu Shan and Zhang Lingxi head-on. "Who's next to him?" The faces of Gao Chuan and his group suddenly became interesting. "She's a senior from the School of Materials Science and Engineering. I'm sending her back to the dormitory." Lu Shan's expression remained unchanged. "Oh...then go ahead." After Lu Shan sent people to the girls' dormitory, he started walking back, thinking about going back to the company tonight. Halfway through the journey, I was surrounded by several people. They were Gao Chuan and his gang. They didn't go back to the dormitory at all, but were waiting here. If I didn't find out clearly, I guess none of us would be able to sleep tonight. "Lu Shan, you are awesome! All the seniors are yours! I thought they were junior girls!"
"What a nice temperament! When did you meet him? Don't you do research every day? How do you still have time?" "Where are Senior Sisters Qiao and Ma?" "I don't have any other requests. I just want to know if the senior from before has any good friends you can introduce to me?" After a barrage of questions, Lu Shan finally had time to answer them: "This is a senior from the Materials Chemistry Team. She is helping me with the experiment. It's too late, so I'll send her off..." Gao Chuan smiled evilly: "Okay, I believe it. Is it okay if I believe it?" Lu Shan was speechless: "I really don't have time to think about anything else." "I have time to think about it, but you don't introduce it. It's really infuriating. Some people wait for fish in the sand pit, while others wait for the sea without eating fish. It's unfair!" "You are so wasteful, you will be punished!" Suddenly there was another burst of ghostly howling. Lu Shan didn't have time to talk nonsense with them, so he went back to the dormitory first. Since this group of people hadn't gone to bed yet, he didn't have any psychological burden to go back to the dormitory. Zhang Lingxi was in the dormitory, watching what was happening below, and no one knew what he was thinking. (End of this chapter)
