Chapter 191: Gallium nitride

In fact, in the past few days, Chen Xin has not only accompanied Wang Xiaoyue in the capital and waited for the latest box office data of "The Village Teacher", but also maintained a high degree of attention to Osborne's contact with the Jiangcheng City Government.

At the beginning, Chen Yuanliang, the mayor of Jiangcheng City, was still a little hesitant about Transwarp's proposal. Although this group holds 60% of Cybertron Digital's shares, the other party said that they would buy up to 7.6 square kilometers of land in the entire Wujiang Industrial Park and build a science fiction film and television city, which is really too big. According to the other party, Transwarp Group will invest tens of billions of dollars in land alone, and it is impossible to calculate how much money will be invested in the future.

This level of investment, even for Jiangcheng, which is in the sub-central city of the Yangtze River Delta Economic Circle, is almost worth half a year's foreign investment.

Of course, for Wujiang District, Transwarp's investment is even more significant.

However, this also aggravated Chen Yuanliang's doubts. Transwarp Group does not have much fame in the world at all, although it holds 60% of the shares of Cybertron Digital, but it still feels unreliable, if the project is halfway into the capital chain breaks, the other party pats the ass and leaves, then the fun will be great.

Osborne was keenly aware of Chen Yuanliang's mentality, and in the email sent to Gangyi, he mentioned several times that the Jiangcheng city government was not particularly enthusiastic about this cooperation.

Chen Xin had already been prepared for this, and in the email he replied to Osborne, he also asked him to wait patiently, and there would be a turnaround soon.

Sure enough, a few days later. A dramatic scene ensued.

The popularity of "The Country Teacher" has continued to rise at the global box office, and the media's attention to Cybertron Digital has also increased.

Later, there was good media speculation that with Cybertron Digital's jishu ability and the two films "Bring Her Eyes" and "Country Teacher", Cybertron Digital has grown into a first-class film and television company in China, and if Cybertron Digital is listed, the market value will at least exceed 10 billion yuan.

And Transwarp owns 60% of Cybertron Digital's shares, and this alone is worthy of Chen Yuanliang's attitude towards Transwarp Group to make a 180-degree turn.

You must know that in the capital market, 6 billion yuan can leverage at least 60 billion yuan. As long as the science fiction film and television city project can be successfully promoted. Even if Zuihou Transwarp Group's financial support can't be sustained. There will also be a large number of domestic enterprises to take over this project.

Therefore, in the following days, Chen Yuanliang not only took the initiative to accompany Osborne and them to Wujiang Industrial Park for investigation, but also assured Osborne that if Transwarp Group was willing to invest in Wujiang Industrial Park. The Jiangcheng city government will provide a series of preferential conditions for Transwarp.

Osborne knew what it meant. A negotiation team of more than 10 people was immediately transferred from the British headquarters. Negotiated with the Jiangcheng city government on the price of land and the next cooperation in the science fiction film and television city.

Of course, for Chen Xin, his own people are charging ahead. Naturally, he can't be idle.

After playing in the capital for more than ten days, Chen Xin left the capital and returned to Jiangcheng after bidding farewell to Wang Xiaoyue.

After staying in Jiangcheng for less than a day, Chen Xin put on the mask he snatched from the old cat, and soon changed his appearance.

This new face also has a legal identity, and the ID card made by the steel hammer can even be directly found on the internal website of the Ministry of Public Security.

Chen then boarded a high-speed train bound for the central inland provinces and got off at an unknown county-level city.

Then Chen Xin rented a two-bedroom apartment with his new identity and spent money on a second-hand medium-sized container truck.

After a series of arrangements were completed, a batch of high-purity gallium metal ordered by Chen Xin at a high price through the Internet also arrived smoothly.

This metal element, which was once predicted by Mendeleev, is mainly used in the electronics industry and communications, and its compound gallium arsenide is a very important second-generation semiconductor, and it is also the main raw material for Chen Xin's phased array radar T/R components.

Historically, gallium arsenide entered the practical stage in 1964.

Gallium arsenide can be made into semi-insulating and high-resistance materials with a resistivity higher than silicon and germanium by more than 3 orders of magnitude, which is used to make integrated circuit substrates, infrared detectors, γ photon detectors, etc.

Because its electron mobility is 5~6 times larger than that of silicon, it has been used in the fabrication of microwave devices and high-speed digital circuits.

Semiconductor devices made of gallium arsenide have the advantages of high frequency, high temperature and low temperature performance, low noise, and strong radiation resistance. In addition, it can also be used to make transfer devices, bulk effect devices.

However, although gallium arsenide is a material with many advantages in semiconductor materials, the crystal transistor made from it has a small magnification and poor thermal conductivity, which is not suitable for making high-power devices.

Therefore, for the T/R components of radar, the defectiveness of the low power of gallium arsenide devices is apparent.

At this time, a new generation of semiconductor material, gallium nitride, began to enter the attention of scientists from all over the world.

GaN is a semiconductor with a large bandgap and belongs to the so-called wide bandgap semiconductors. It is an excellent material for microwave power transistors, and it is also a semiconductor with important application value in blue light-emitting devices.

At present, the research and application of GaN materials is the frontier and hot spot of global semiconductor research, and it is a new semiconductor material for the development of microelectronic devices and optoelectronic devices.

It has wide direct band gap, strong atomic bonds, high thermal conductivity, good chemical stability (almost not corroded by any acid) and strong radiation resistance, and has broad prospects in optoelectronics, high-temperature and high-power devices and high-frequency microwave device applications.

For the military of the information age, the importance of this material is even more prominent.

Not long ago, it was reported that the American company Raytheon received an honor from the Office of the Secretary of Defense for its achievements in participating in the gallium nitride (GaN) manufacturing improvement project.

In the U.S., Raytheon has verified the reliability of its GaN production process. As long as the manufacturing cost is compressed to a certain extent, it is believed that in a few years, the era of gallium nitride will soon come.

Of course, for Chen Xinhe Gang, providing the military with T/R components made of gallium nitride on a large scale is not a problem at all, and it is even much simpler than gallium arsenide. (To be continued......)
