I am a great scientist

Chapter 108 Nanofabrication
Zhou Xing didn't know about the small actions behind his parents' back. After finishing dinner quickly, he hurried back to the dormitory.

After so many days of research on nanobiotechnology, Zhou Xing has already got a clue, and Zhou Xiaozhi in the virtual laboratory is waiting for him to experiment together.

Zhou Xing returned to the dormitory, lay down on the bed impatiently, and fell into 'dreamland' within a few seconds.

"Boss, you're back!" Seeing Zhou Xing appearing out of thin air, Zhou Xiaozhi said happily, his black eyes lit up.

"Well, let's continue!" Zhou Xing said with a smile.

"Okay!" Zhou Xiaozhi accepted the order happily.

Zhou Xing walked to a scanning probe microscope and started the experiment.

Newton magazine once used the earth as a metaphor: the comparison of "one meter" and "one nanometer" is equivalent to the diameter of the earth and the diameter of a glass marble.

When conducting research on nanotechnology, it is impossible to see clearly even with a general microscope. At this time, a scanning probe microscope is an indispensable instrument.

Scanning probe microscopy uses a probe as a sensor to detect the microstructure and local properties of the surface of the sample to be tested. In order to achieve nanoscale spatial resolution, the tip of the probe is very sharp, and the radius of curvature of the tip can be several On the order of ten nanometers, when the scanning probe microscope works, the probe-sample distance is generally controlled between 0.1 and 10 nanometers.

"Little Zhi, start the experiment and prepare to record!" Zhou Xing manipulated the nanoprobe while processing the test target with a laser.

"Okay, boss!" Zhou Xiaozhi complied, his small black eyes staring nervously at Zhou Xing's experiment process.

Zhou Xing focused on the display screen, controlled the probe to scan and observe with one hand, manipulated the keyboard with the other to input instructions, and processed nanomaterials with laser beams.

Time flew by bit by bit, and Zhou Xiaozhi next to him watched and recorded with bated breath.

"It's bad! Boss, the photon energy is too high, and the nanomaterial structure is destroyed!" Zhou Xiaozhi suddenly shouted anxiously.

"How much is the damage? Can it be saved?" Zhou Xing frowned and asked hastily.

"Boss, I can't do it! The main structure of the nano-device has collapsed and can no longer support it." Zhou Xiaozhi said with a look of disappointment.

"Well, then try again, summarize the failure process of this experiment, and select solutions." Zhou Xing's face remained unchanged, and he ordered Zhou Xiaozhi.

"Boss, I suggest changing to another nanomaterial, or another nanoprocessing method." Zhou Xiaozhi offered Zhou Xing a choice.

Hearing this, Zhou Xing's expression darkened, and he finally selected a biocompatible and biodegradable nanomaterial from countless nanomaterials. It's that simple to choose another material to replace.

There is no way but to change to another processing method.

"We will experiment with other processing methods." Zhou Xing ordered.

"Boss, what method are you going to use this time?" Zhou Xiaozhi's face tightened, and he obeyed.

There are various ways of nanofabrication: nanofabrication with scanning tunneling microscope and atomic force microscope is available; chemical synthesis method can be used to assemble the material units of microscopic system into nanodevices "bottom-up"; it can be processed by focused ion beam technology; Excimer laser can be used for processing with its high resolution, cold processing, "direct writing" characteristics,...

"Xiaozhi, create a five-nanometer lithography machine, let's modify it and process it with engraving technology." Zhou Xing ordered Zhou Xiaozhi.

"Boss, are you sure? The workload will be very heavy! I suggest using stamping technology!" Zhou Xiaozhi was stunned for a moment, and suggested to Zhou Xing.

"No! The printing and pressing technology can't achieve the effect I want, so listen to me." Zhou Xing thought for a while, then shook his head firmly.

"Okay!" Zhou Xing didn't accept his opinion, so Zhou Xiaozhi pouted, but still acted according to the order.

Soon, in the virtual laboratory, a huge lithography machine appeared in front of Zhou Xing out of thin air.

"Boss, what are we going to do next!" Zhou Xiaozhi looked at Zhou Xing curiously:

Zhou Xing looked at the lithography machine in front of him, and ordered: "Peel off the cabinet, and remove the parts of the material inlet!"

Zhou Xiaozhi listened to the order, and the cabinet of the lithography machine disappeared by itself, revealing the bare metal, followed by the incoming parts.

"Remove the light baffle, expose the laser,..." Zhou Xing continued to order.

"Okay, boss..." Zhou Xiaozhi continued to take orders.

In the virtual laboratory, relying on his intimate knowledge of the 5nm lithography machine, Zhou Xing, with the assistance of Zhou Xiaozhi, began to make major improvements to its functions.

Time flies bit by bit, and a day passes in a blink of an eye.

Zhou Xing lay in bed all night. After waking up in the morning, he solved his personal problems. After hastily eating some bread for breakfast, he lay on the bed again and returned to the virtual laboratory impatiently.

The weather is sunny and crisp.

The campus of Peking University is very lively in the early morning. The chirping of various birds on the branches is pleasant to the ear. Under the shade of the trees, people are playing badminton, reading books, running on the playground, playing ball..., students are all over the campus. Sway energy.

In the girls' dormitory building, many girls slept later than usual, washing in pajamas, some cleaning the dormitory, some reading under the covers, and some drying the quilt on the balcony. Today is a lazy Sunday.

"Xiaoxin, get up quickly, we have group activities in our dormitory today." Guan Xiaoyu came out of the bathroom after washing up, and said to Tang Xin who was still sitting on the bed reading.

"What event? Where are you going?" Tang Xin continued to look at the book without raising her head, and responded casually.

"Why are you asking so many questions? Get up quickly. You have to act together with us today. You know how to read books and be a house girl all day long. You've lost your face and figure for nothing." Guan Xiaoyu stared at Tang Xin angrily and said.

"Yes! Xiaoxin, let's go out and relax this weekend!" Liu Zihui persuaded Tang Xin.

At this moment, a pleasant bell rang.

"En! Let's talk later, I'll answer the phone first!" Tang Xin put down the book, revealed a delicate face, and confessed to Liu Zihui.
