I Have a Research Support System

At 8 o'clock in the morning on May 1st, in the dormitory.

Because it was a rare holiday period, Xu Qiu also slacked off, playing on the phone on the bed and not wanting to get up.

His two roommates, Tao Yan, are natives of Shanghai, and went home directly. Originally, Tao Yan had a travel plan, but considering that the graduation project had not been completed, he temporarily postponed it, and planned to wait until the defense was finished before graduating. Traveling; Ren Bin is from Xinjiang Province, and it is inconvenient to go home, so he also chose to stay at home.

At this time, Ren Bin was sitting in front of the desk, and suddenly called out: "Xu Qiu, come and help me."

"What's the matter?" Xu Qiu was a little puzzled, but he 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?"

"That's right, I haven't written a word of my graduation project yet," Ren Bin sighed, and then said, "Xu Qiu, you must have finished your project."

"I haven't started writing yet." Xu Qiu spread his hands, he probably knew what Ren Bin wanted him for.

"Ah...the graduation thesis is due to be submitted in less than a month," Ren Bin scratched his head in embarrassment, thinking in his mind: "Could it be that Xu Qiu was busy doing experiments and forgot about this..."

‘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 oppressing students. The students in his group are living in dire straits..."

‘Xu Qiu was so overwhelmed by the pressure of the heavy experiments, and then assumed his identity as a direct Ph.

'When all possibilities have been eliminated and one remains, no matter how improbable, that is the truth. '

Thinking of this, Ren Bin said in a positive tone: "You are too busy doing experiments to forget about it."

Xu Qiu:? ? ?

I don't know how he came to this conclusion...Xu Qiu explained: "I have ready-made Chinese versions of my experimental data and description texts, and it will take two or three days after the festival to quickly compile them."

"Yuan, so that's the case." Ren Bin couldn't help blushing, a little embarrassed, and couldn't help feeling in his heart: "My imagination is still a little lacking. 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 about Ren Bin's rich inner drama, so he took the initiative to say: "Your graduation project..."

"Can you help me to take a look? I tested some data, but I'm not very good at writing." Ren Bin followed the steps.

"Let me first take a look at your existing experimental data." Xu Qiu said, although at his current level, the difficulty of directing undergraduate thesis is almost zero. After all, he has even reviewed doctoral thesis, but he has not He directly agreed, but planned to investigate first.

If Ren Bin's experimental work is sufficient, he would not mind helping out and giving some technical guidance. After all, they are roommates who have lived together for three years. He is still willing to help with this small favor; on the contrary, if you give him an empty shell If you ask him to create a graduation thesis from scratch, then he will naturally not agree.

Ren Bin opened a folder named "Graduation Project" and said, "Here, all the documents and experimental data related to the graduation project are in it."

Then, Ren Bin got up and gave up his gaming chair, "Xu Qiu, sit down."

"Okay." Xu Qiu was not polite, directly took over the computer, opened several important files, and checked them.

The first is Ren Bin's opening report, entitled "Preparation of Titanium-doped ZnO Thin Films by Atomic Layer Deposition and Research on Their Properties".

There are some literature reviews, including the application of zinc oxide thin films, and several methods to obtain nano-thin films, physical vapor deposition (PVD), chemical vapor deposition (CVD), atomic layer deposition (ALD).

"Your work is quite related to my field." Xu Qiu said with a smile.

"Really, that's great." Ren Bin said happily. He knew that the higher the correlation, the more Xu Qiu knew, and the easier it was to guide him to write his graduation thesis.

While continuing to browse the documents, Xu Qiu introduced to Ren Bin: "When we prepare solar cells, the method we use is physical vapor deposition. At the same time, zinc oxide is also an important transport layer material for organic photovoltaic inverted structures. However, we use The preparation method obtained is the sol-gel method..."

"Hmm...um..." Ren Bin understood roughly, and nodded frequently in response.

Soon after Xu Qiu finished reading the opening report, he concluded: "In the literature review part of the opening report, you can add a part of the content and put it in the graduation project as the introduction. Of course, it doesn't matter. This part is not bad. "

After a pause, Xu Qiu turned around and asked, "Did you write this part yourself?"

Ren Bin honestly admitted: "Not exactly, a sister from our group with a master's degree helped me polish it."

"No wonder, the language looks more academic, not like it was written by a novice." Xu Qiu nodded and asked curiously: "Then why didn't you continue to ask her for advice?"

"She also graduated this year and has already found a job. Now she is busy with her graduation defense and an internship. She will basically not come to school in April. I am too embarrassed to continue to disturb others, but she is quite nice. Leave Helped me design the experiment before." Ren Bin said.

"Why, have you taken a fancy to senior sister?" Xu Qiu teased, hearing something unusual in Ren Bin's tone.

"He has a boyfriend." Ren Bin whispered.

Xu Qiu muttered to himself, it seems that there is indeed a situation, but this kind of gossip is not what he is keen on, so he didn't continue to ask, and changed the subject: "Is there a template for the graduation thesis?"

"No." Ren Bin shook his head.

"En." 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 There is."

Ren Bin looked at the information on the front page of the template and said, "Tian Qing, the student number is 1xx... This is our senior from the previous class."

"That's right, a master's student in our group." Xu Qiuying agreed, and then explained while operating the mouse and keyboard: "We directly copy the text from the opening report into the introduction part of the graduation thesis, just like this. "

After finishing it, Xu Qiu continued: "We still need to write the abstract and keywords in Chinese and English, as well as the bibliography of the thesis. This will be empty for now, and we will write it later."

"Okay." Ren Bin took a small notebook and began to record.

Xu Qiu glanced at Ren Bin's actions, and said, "No need to record, I just write the precautions in the Word template."

Afterwards, Xu Qiu opened a folder named "Experimental Data", and found that there were various formats of raw data in it, and the file suffixes were very rich, including TXT, XLS, CSV..., and even in PDF format. , most of the data files are named in Chinese.

Influenced by Teacher Wei, Xu Qiu's usual experimental data files are all named in English and neatly categorized. Now at first glance, seeing so many data piled up chaotically, he still feels a little uncomfortable.

However, Xu Qiu quickly adjusted and noticed a special file, "Experimental Protocol and Significance of Various Characterization Work.docx", double click to open it.

"This is the experiment plan that my sister made for me during the opening report in March, and I followed her plan to carry out the experiment." Ren Bin took the initiative to explain.

"Understood." Xu Qiu nodded and browsed through. There were not many items in it, including:

The preparation of zinc oxide film, use titanium isopropoxide, diethyl zinc and deionized water as precursor solution, utilize ALD method, deposit on silicon wafer, quartz substrate, change the content of titanium isopropoxide, can Control the content of titanium element in the film.

Ultraviolet-visible-near-infrared 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 tested, except that a near-infrared light detector is newly added, and the detection range can be extended from about 200-900 nanometers to about 200-2000 nanometers.

Ellipsometer, testing the thickness and some optical properties of ZnO thin film. Xu Qiu had considered this when testing the thickness before, but in the end he gave up and chose the SEM method, mainly because fitting is involved in the ellipsometer test process. For Xu Qiu's effective layer materials, every new material They all correspond to completely different fitting parameters, and it takes a lot of energy, which is not very worthwhile.

X-ray diffraction, that is, XRD, is used to crystallize properties of zinc oxide films to explore the influence of substrate, impurity concentration, and film thickness on crystallization.

The effect of Hall effect test on charge mobility and conductivity of zinc oxide film with doping concentration was obtained, and the optimal doping concentration was finally screened out. This test is somewhat related to Duan Yun's thermoelectric materials. The samples prepared by Duan Yun are also going to test the Hall effect to obtain the conductivity of the material.

After reading the guidance document given by Senior Sister Ren Bin, Xu Qiu continued to click on each document in turn and check it against the file name.

In the end, Xu Qiu concluded: "According to your senior sister's experimental ideas, what is the problem? The current experimental data can be processed first. In terms of data volume, it is relatively small, only four or five pictures, but this is also a problem. There’s 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 realized that it was normal for Ren Bin not to have contact with ORIGIN.

Xu Qiu rubbed his chin and said, "It's not impossible, but it's better to use professional data processing software like ORIGIN. How about this, you press EXCEL to get the data out, and then I'll help you draw the picture." Anyway, there are only a few It took only ten minutes for him to deal with a picture.

"After processing the pictures, we will start to write the second part 'experimental part', which includes the drugs, reagents, film preparation process, and specific methods of various characterization and testing methods." Xu Qiu operated in the template, While telling Ren Bin what needs to be added in this part:

"The third part is the experimental data analysis part. This will be done after the second part is completed and the data pictures are processed."

"The fourth part is the conclusion, and the last part is the references 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 the ideas for writing the graduation project.

Ren Bin's work gave Xu Qiu the feeling that overall the degree of completion is not bad. Although Ren Bin usually does nothing, he is quite reliable when it comes to major matters such as whether he can graduate smoothly.
