The next morning,

Fang Qing came to the school staff cafeteria early and sat in the corner for breakfast. After a while... he saw Zheng Jianghe coming to him with a plate, sitting opposite him.

"Xiao Fang."

"Thank you last night and I took me home." Zheng Jianghe woke up in the morning and found himself lying in bed, knowing that Fang Shi sent him back.

"fine."

"Don't be so polite between us." Fang Qing disagreed. He ate his egg cake and looked up at Zheng Jianghe who was extremely haggard in front of him, and said caringly: "Brother Zheng...why you take a break today, look at your mental state doesn't look like you work."

"Um..."

"Come here to check in, then take a nap in the afternoon, and go to the meeting in the afternoon." Zheng Jianghe called out and said tiredly: "I suspect that I drank fake wine last night, and only six bottles of beer, but I actually drank me in pieces."

After a simple chat, the two of them started to have breakfast, then left the restaurant and returned to their jobs.

In the utility room of the second department, Fang Qing sat at his desk and wrote down three methods that he thought of last night. The core of these three methods is to use two-dimensional layered material, which is a layered material connected in the plane with covalent bonds and interlayers interact with van der Waals forces.

Due to the different arrangements of transition metals and chalcogenous atoms, the material crystals have diversity, such as...topological insulating states, semiconductor states, semi-metallic states and superconducting states.

In the following time, Fang Wei carried out precise calculations of the three methods and finally chose the third method as his main means of breaking. However, the progress was not as smooth as he imagined, and soon he encountered difficulties.

He needs to use a special elliptical polarized light to illuminate the material body, but this belongs to the field of optics. Only the third department in the institute has such equipment.

Hesitant film,

Fang Qing stood up and went to Mr. Yu's office, hoping that he could help him talk to him and borrow equipment from the third department.

Bang bang bang!

He knocked on the office door, then pushed the door open and saw the old man calling as soon as he opened the door.

Seeing Fang Xu's arrival, Yu Huazheng nodded to him, made another move to let him sit down, and called on his own.

"good!"

"I understand, that's it."

After the words,

He hung up the phone directly, then looked up at Fang Qing, and asked with a smile: "Xiao Fang? What's the matter?"

"Old Yu..."

"I need an elliptical polarizer. Can you communicate with the director of the third department?" Fang Qing did not say anything nonsense, but directly opened the skylight and told Mr. Yu about the purpose of his visit.

"no problem."

"What a big deal." Old Yu smiled, then asked curiously: "But I'm a little curious, what do you want to do with an elliptical polarizer?"

“That’s how it is.”

"I found a way to realize spontaneous cyclone sorting, by irradiating special elliptical polarized light on the two-dimensional layered material and cooling it to a certain critical temperature to create a chiral domain inside the two-dimensional layered material."

Speaking of this, pausing, Fang Qi continued: "The chirality in this state can be verified by the circular photocurrent outside the plane, and the direction... According to my thoughts, it should depend on light sensing."

Yu Qianqian sat angrily on the sofa, her fat-like pleated lips and her face was full of anger.

I really wanted to put a sack on his head and punch him twice.
