Chapter 271: Xu Qiu can do it in 3 days?

At 8 o'clock in the morning on May 1st, the bedroom.
　　Because it was a rare holiday, Xu Qiu also slack off, lying in bed playing with her mobile phone and didn't want to get up.
Two of his roommates, Tao Yan, a native of the Magic City, went home straight away. Tao Yan had a travel plan originally, but considering that the graduation project has not been completed yet, he temporarily postponed it and plans to wait until the defense is completed before graduation. Traveling; Ren Bin is a native of Xinjiang Province, so it is not convenient to go home, so he chose to stay.
　　 At this time, Ren Bin was sitting at the writing desk and suddenly called out: "Xu Qiu, come and help me."
　　 "What's the matter?" Xu Qiu was a little confused, but got out of bed and walked towards Ren Bin. He found that there was a blank WORD document on Ren Bin's computer desktop, and he was not playing games.
　　 Seeing this, Xu Qiu thought for a moment, and guessed: "Graduation project?"
　　 "Yes, I haven't written a word in my graduation project yet," Ren Bin sighed, and then said, "Xu Qiu, you must have finished writing it."
　　 "I haven't started writing yet." Xu Qiu spread his hands, he probably knew what Ren Bin was looking for.
　　 "Ah, this... the graduation thesis is about to be submitted in less than a month," Ren Bin scratched his head awkwardly, thinking in his heart: "Could it be that Xu Qiu was busy doing the experiment and forgot about it..."
　　‘Hiss, it’s very possible. Based on this assumption, Ren Bin continued to fill in the picture:
　　‘It is said that Wei Xingsi is a very BT tutor who has been squeezing students. The students in his group are living in dire straits...’
　　‘Xu Qiu was overwhelmed by the pressure of the experiment, and then substituted his status as a direct Ph.D student in advance, thus forgetting that he was a senior student, and forgot about the graduation project...’
　　‘When all possibilities are eliminated and one is left, no matter how impossible it is, that’s the truth. ’
　　 Thinking of this, Ren Bin said in an affirmative tone: "You are busy doing the experiment and forget about it."
　　 Xu Qiu:? ? ?
　　 I don’t know how he came to this conclusion... Xu Qiu explained:
My experimental data and description text are all available in Chinese. Just wait two or three days after the festival to finish it quickly.

"Original, it turned out to be like this." Ren Bin couldn't help but blush, a little embarrassed, and he couldn't help feeling in his heart: "I still lack my imagination. It usually takes two or three months to barely complete the graduation project, Xu Qiu actually It can be done in two or three days. ’
　　 Xu Qiu didn't know Ren Bin's rich inner drama, and actively said: "Your graduation project..."
　　 "Can you help me? I tested some data, but I don't know how to write." Ren Bin followed the steps.
"Let’s take a look at your existing experimental data." Xu Qiudao, although at his current level, the difficulty of guiding undergraduate thesis is almost zero. After all, he has even reviewed his doctoral thesis, but he hasn’t. He agreed directly, but planned to investigate first.
If Ren Bin’s experimental work is adequate, he doesn’t mind helping out and giving some technical guidance. In other words, he is a roommate who has lived together for three years. He is still willing to help if this is a small favor; on the contrary, if he is given a shell Son, let him get a graduation thesis from scratch, then he naturally cannot agree.
　　 Ren Bin opened a folder named "Graduation Design" and said, "Here, the files and experimental data related to the graduation project are in this."
　　 Then, Ren Bin got up and let out his gaming chair, "Xu Qiu, sit down."
　　 "Okay." Xu Qiu was not welcome, and took over the computer directly, opened a few major files, and checked them.
　　 First is Ren Bin’s opening report, the topic is "Atomic Layer Deposition Preparation of Titanium-Doped Zinc Oxide Films and Research on Their Characteristics".
　　There are some literature reviews, including the application of zinc oxide films, and several methods to obtain nano-films, physical vapor deposition (PVD), chemical vapor deposition (CVD), and atomic layer deposition (ALD).
　　 "Your job is quite relevant to the field I do." Xu Qiu smiled.
　　 "Really, that's great." Ren Bin said happily. He knew that the higher the correlation, the more Xu Qiu understood and the easier it would be to guide him in writing his graduation thesis.
Xu Qiu continued to browse the files while introducing Ren Bin:
When we prepare solar cells, the method used is physical vapor deposition. At the same time, zinc oxide is also an important transport layer material for organic photovoltaic inverted structures, but we use The preparation method obtained is the sol-gel method..."
　　 "Hmm...mm..." Ren Bin understood roughly, and nodded in response frequently.
Soon, Xu Qiu read the opening report and concluded: "In the literature review part of the opening report, you can add a part of the content and put it in the graduation design as the introduction part. Of course, it does not change. This part is fine. "
　　 After a pause, Xu Qiu turned around and asked, "You wrote this part yourself."
　　 Ren Bin admitted honestly: "Not exactly, we have a master's sister who helped me polish it."
　　 "No wonder, the language looks more academic, not like new handwriting." Xu Qiu nodded and asked curiously: "Then why didn't you continue to ask her."
"She also graduated this year and has already found a job. Now she is busy with school graduation defense while doing an internship. She basically won't come to school in April. I am not too embarrassed to continue disturbing others, but she is pretty good and leaves. Helped me design the experiment." Ren Bin said.
　　 "Why, do you like Senior Sister?" Xu Qiu heard something unusual in Ren Bin's tone, and said, moving.
　　 "I have a boyfriend." Ren Bin whispered.
　　 Xu Qiu murmured to himself, it seems that there is a real situation, but this kind of gossip is not what he is keen on, so he did not continue to ask, and changed the subject: "Is there a template for graduation thesis?"
　　 "No." Ren Bin shook his head.
"Yeah." Xu Qiu got up, found Tian Qing's graduation thesis from his computer, deleted the text content, leaving only the frame part as a template, copied it to a USB flash drive, opened it on Ren Bin's computer, and said: "Now Yes."
　　 Ren Bin looked at the information on the homepage of the template and said, "Tian Qing, the student ID is 1xx...This is our last senior sister."
"Yes, the master's sister in our group." Xu Qiuying made a peace, and then he operated the mouse and keyboard while explaining: "We copied the text in the opening report directly into the introduction of the graduation thesis, like this. "
After 　　 was done, Xu Qiu continued: "The abstract and key words in Chinese and English, as well as the catalogue of the paper need to be written in the front. This will be left blank and will be written at the end."
　　 "Okay." Ren Bin took a small notebook and started recording.
　　 Xu Qiu glanced at Ren Bin's actions, and said: "No need to record, I just write the precautions in the WORD template."
Later, Xu Qiu opened a folder named "Experimental Data" and found that it contained various formats of original data. The suffixes of the files were very rich, including..., even PDF format, most of the data The files are named in Chinese.
　　 Under the influence of Teacher Wei, Xu Qiu’s usual experimental data files are all named in English and neatly classified. At first glance, I see so many data piled together in a mess, and I still feel a little uncomfortable.
　　 However, Xu Qiu quickly adjusted it and noticed a special file, "Experimental Protocol and Meaning of Each Characterization Work.docx", double-click to open it.
　　 "This is the experiment plan that my senior sister gave me during the opening report in March. I did the experiment according to her plan." Ren Bin actively explained.
　　 "Understood." Xu Qiu nodded, and after browsing, there were not many items in it, including:
The preparation of zinc oxide thin film, using titanium isopropoxide, diethyl zinc and deionized water as precursor solutions, using ALD method to deposit on silicon wafers and quartz substrates, changing the content of titanium isopropoxide, Adjust the content of titanium in the film.
　　 Ultraviolet Visible Near-Infrared Light Absorption Spectroscopy Test (UV-vis-NIR), to detect the light absorption properties of zinc oxide films. It is similar to the UV-vis that Xu Qiu usually tests, except that a new detector with near-infrared light is added, and the detection range can be expanded from about 200-900 nanometers to about 200-2000 nanometers.
　　 Ellipsometer, to test the thickness and some optical properties of the zinc oxide film. Xu Qiu considered this before when testing the thickness, but finally gave up and chose the SEM method, mainly because the ellipsometer test involves fitting. For Xu Qiu’s effective layer material, every new material They all correspond to completely different fitting parameters. It takes a lot of effort and is not very worthwhile.
　　 X-ray diffraction, or XRD, is used to investigate the crystalline properties of zinc oxide films and to explore the influence of substrate, impurity concentration, and film thickness on crystallization.
　　Hall effect test, obtained the influence of the charge mobility and conductivity of the zinc oxide film with the doping concentration, and finally screened the optimal doping concentration. This test is somewhat related to Duan Yun's thermoelectric materials. The samples prepared by Duan Yun are also required to test the Hall effect to obtain the material's conductivity.
　　 After reading the guidance documents given by Senior Sister Ren Bin, Xu Qiu continued to click on each document in turn and check it against the file name.
Finally, Xu Qiu concluded: "According to your senior sister's experimental thinking, what is the problem, the current experimental data can be dealt with first. In terms of data volume, relatively speaking, it is relatively small~EbookFREE.me~ only about four or five. Zhang Tu, but this is no way, let's talk about it later." After a pause, Xu Qiu turned around and asked:
　　 "By the way, you know how to process data and draw pictures."
　　 "Import the data into EXCEL, and then generate a scatter plot?" Ren Bin tentatively asked.
　　 "EXCEL?" Xu Qiu asked subconsciously, and then reacted. It is normal that Ren Bin has not been in contact with ORIGIN.
Xu Qiu touched his chin and said, "It's not impossible, but it's better to use professional data processing software like ORIGIN. Then, you can get the data by EXCEL first, and then I will help you draw the picture." Anyway, there are only a few. A picture, it took him only ten minutes to deal with.
"After processing the pictures, we must start to write the second part of the "experimental part", which includes the drugs, reagents, film preparation process, and the specific methods of various characterization test methods." Xu Qiu worked in the template, Tell Ren Bin what needs to be added in this part:
　　 "The third part is the experimental data analysis part. This is when the second part is done, and the data pictures are processed."
　　 "The fourth part is the conclusion, and the last part is the reference and acknowledgments. Let's write this part at the end."
　　 It took a total of more than half an hour, and Xu Qiu helped Ren Bin sort out his graduation design ideas.
　　 Ren Bin’s work gave Xu Qiu the feeling that he was generally well-completed. Although Ren Bin is usually a fool, he is quite reliable in terms of whether he can graduate successfully.
