System Release Task.

[Mission: Research and development of fourth-generation semiconductor materials]

[Mission Reward: Data of the New Generation Space Urine Collection Device]

【Reward: Random Ability Boost】

？？？

A bunch of question marks popped up directly on Lin Yu's head.

Since the end of research on artificial organs, isn't this system a little too self-indulgent?

Forget about the solar panel intelligent light chasing system, what the hell is this aerospace urine collection device?

Also, where did I trigger this semiconductor material development task, could it be that what the team leader said stimulated it?

However, the team leader is talking about the storage and transportation of high-voltage electricity, and it is not so closely related to semiconductor materials.

Forget it, let's go back to the hotel.

Lin Yu followed the exploration team to stop and go, and the experts of the Ganzhou Provincial Geological Exploration Institute also took instruments to continuously measure the geology and terrain, so it took a whole day.

After the exploration, the group rushed back to the hotel in an off-road vehicle, which was tiring for a day, and the site was still not decided.

Back at the hotel, Lin Yu, who had been tired for a day, quickly finished washing, lay down on the bed, put his hands behind his head, looked at the ceiling, and muttered to himself:

"The fourth generation of semiconductor materials, this is about to become my old field, and when I go back, I will do it with Sister Xu and them, even if it is the stepping stone to the first time in materials science."

The first generation of semiconductor materials: represented by silicon (Si) and germanium (Ge). It can manufacture cutting-edge CPUs, GPUs, memory chips, and power devices in various chargers.

Second-generation semiconductor materials: represented by gallium arsenide (GaAs) and indium phosphide (InP). Gallium arsenide and indium phosphide semiconductor lasers have become key devices in optical communication systems, while gallium arsenide high-speed devices have also accelerated the development of new industries in optical fiber and mobile communications. The main application fields are optoelectronics, microelectronics, microwave power devices, etc.

Third-generation semiconductor materials: represented by gallium nitride (GaN) and silicon carbide (SiC). This material is marked by the successful development of high-efficiency blue-green light-emitting diodes and blue-light semiconductor lasers, which have excellent properties such as high breakdown electric field, high thermal conductivity, high electron saturation rate and strong radiation resistance, and are more suitable for the production of high-temperature, high-frequency, radiation-resistant and high-power electronic devices, and are the "core" of solid-state light sources and power electronics and microwave radio frequency devices.

The first and second generations of semiconductor materials have been used for a long time, and the rise of the Internet is closely related to the first and second generations of semiconductor materials, complementing each other.

And this third-generation semiconductor material has only been produced in the last few years from laboratory preparation to mass production.

The research of the fourth generation of semiconductor materials has also begun to emerge, but there is still a lot of way to go from theory to practice.

Can I surpass the fourth-generation semiconductor material R&D center that was established last year?

Fourth-generation semiconductor materials: represented by gallium oxide (Ga2O3).

As a new type of wide bandgap semiconductor material, gallium oxide (Ga2O3) has attracted great attention and research in the fields of ultraviolet detection and high-frequency power devices due to its excellent performance and wider bandgap than the third-generation semiconductor materials SiC and GaN.

In particular, the development of high-tech such as quantum information and artificial intelligence, and the new semiconductor system and its multi-functional device technology such as microelectronics are also being updated and iterated.

Lin Yu closed his eyes and stopped thinking about these things, and his consciousness gradually fell into darkness, silent and chaotic.

Lin Yu, who woke up again, felt refreshed, he didn't go to the system research institute last night, and his spirit recovered very well.

After breakfast, Lin Yu was about to set off again, since it couldn't work here, then they had to rush to the next place.

Minqin County, a county under Wuwei, also belongs to the Tengger Desert, and the bad news is that the greenhouse effect has made the land more desertified, and the Tengger Desert is also expanding outward.

In fact, the layout of the photovoltaic power generation industry here also has the meaning of controlling desertification, and in China's 14th Five-Year Plan, photovoltaic + desertification control is also feasible.

In the Kubuqi Desert, which is close to the grassland area, the photovoltaic sand control industry has developed here.

The so-called photovoltaic desertification control refers to the combination of the development of photovoltaic and desert management and water-saving agriculture.

The periphery of the power station is composed of grass checkered sand barriers and sand-fixing forests to form a shelterbelt system, and water-saving drip irrigation facilities are installed under photovoltaic panels to plant green cash crops to achieve a win-win situation of economic and ecological benefits.

It is an innovation in the form of clean energy utilization in the 21st century, and it is the best artificial intervention method to use nature to govern nature.

And only China in the world can do these things.

Lin Yu and the exploration team stayed here for two more days, and finally determined a good place, which was on the periphery of the Tengger Desert.

If it is located here, on the one hand, the photovoltaic industry can bring economic benefits to the local area, and on the other hand, photovoltaic desertification control can bring ecological and environmental benefits, which is indeed a great thing for the local area.

After finishing today's exploration, the group casually found a small restaurant on the side of the street.

"It's very smooth, I usually run a lot, but I didn't expect that this time I wouldn't even need it for two weeks."

Members of the exploration team sighed.

"Yes, we planned to go to Qinghai-Tibet Province and the plateau area at the beginning, which saved a lot of work."

In two weeks, Lin Yu has lost a lot of weight, running around against the sun, and it has also darkened a lot.

But Lin Yu has been following the exploration team and has not complained or anything, which makes the team members look up.

"Lin Yu, I heard that your little girlfriend came with you." The young man in the exploration team laughed teasingly.

He and Lin Yu are not very different, so they can chat with Lin Yu, and their relationship in the team is relatively good.

"Well, she went to the orphanage for charity."

"Where is he?"

"It's in Ganzhou Province."

"Oh? Then we're done here, aren't you going to meet? ”

"Brother Zhao, do you want to take a look at my girlfriend?" Lin Yu also looked at him with a smile.

originally wanted to tease Lin Yu, but now he can't fix it.

"It's okay, Brother Zhao, I won't laugh at a single dog."

"Hahaha." The whole team laughed, and the room was filled with a cheerful atmosphere.

"Xiao Yu, you are not righteous, why don't you show us if you have a girlfriend?" The team leader also coaxed.

"Go, go, team leader, don't you have a wife? Look at your own wife! ”

"How can your own daughter-in-law be as good-looking as someone else's, do you think it's true!"

"That's right!"

"Oh, Xiaolin, you just show us, we won't lose it, and we can't snatch it!"

"Okay, I'll show you." Lin Yu proudly took out his mobile phone, and the photo album was the photo he took of Luo Bing.

"Good boy, you don't have a good eye!"

Lin Yu smiled and looked at the members of the exploration team looking at the photos on their mobile phones, half a month of eating, living and working together, so that this group of young and middle-aged people had a good relationship.
