Chapter 191 Gallium Nitride
In fact, apart from accompanying Wang Xiaoyue and waiting for the latest box office data of "Country Teacher" in the capital these days, Chen Xin has also maintained a high degree of concern about Osborne's contact with Jiangcheng Municipal Axe. .
At first, Chen Yuanliang, the mayor of Jiangcheng City, was a little hesitant about Xinghuan Group's proposal.Although this group holds 60.00% of Cybertron's shares, the other party said that they would buy the entire Wujiang Industrial Park as much as 7.6 square kilometers of land and build a sci-fi film and television city. It's too big.According to the other party, the Xinghuan Group will invest tens of billions of funds in the land alone. As for how much money will be invested in the future, it is impossible to calculate.
This level of investment, even for Jiangcheng City, which is located in the sub-central city of the Yangtze River Delta Economic Circle, is almost worth half a year's worth of foreign investment.
Of course, for Wujiang District, the significance of the Star Ring Group's investment is even greater.
However, this also aggravated Chen Yuanliang's doubts.The Star Ring Group is not well-known in the world at all. Although it holds 60.00% of Cybertron's shares, it still feels unreliable. Let the ass go, then the fun will be great.
Osborn was keenly aware of Chen Yuanliang's mentality, and in the emails he sent to Gangbi, he mentioned several times that the Jiangcheng Municipal Government's enthusiasm for this cooperation was not particularly high.
Chen Xin had been prepared for this, and asked him to wait patiently in the email reply to Osborn, and there will be a turning point soon.
Sure enough, a few days later, a dramatic scene appeared.
With the popular release of "Country Teacher", the global box office continues to rise, and the media's attention to Digital Cybertron is also getting higher and higher.
Later, some good media speculated that with the technical capabilities of Cybertron and the two films "Bring Her Eyes" and "Country Teacher", Cybertron Digital has grown into a first-class film and television company in China. If If Cybertron goes public, its market value will exceed at least [-] billion RMB.
The Star Ring Group owns 60.00% of Cybertron's shares. This alone is worth making a 180-degree turn in Chen Yuanliang's attitude towards the Star Ring Group.
We must know that in the capital market, 60 billion yuan can leverage at least 600 billion yuan of funds.As long as the sci-fi film and television city project can be promoted smoothly, even if the financial support of the Star Ring Group cannot continue in the end, there will be a large number of domestic companies to take over the project.
Therefore, in the next few days, Chen Yuanliang not only took the initiative to accompany Osborne and the others to Wujiang Industrial Park for investigation, but also assured Osborne and the others that if Xinghuan Group is willing to invest in Wujiang Industrial Park, Jiangcheng Municipal Axe will provide Xinghuan Group with a series of preferential terms.
Osborne heard the strings and knew the meaning, and immediately transferred a negotiating team of more than ten people from the British headquarters to start negotiations with Jiangcheng Municipal Axe on the land price and the next cooperation in the science fiction film and television city.
Of course, as far as Chen Xin was concerned, his own people were charging ahead, so he naturally couldn't sit idle.
After playing in the capital for more than ten days, Chen Xin bid farewell to Wang Xiaoyue, left the capital and returned to Jiangcheng.
After staying in Jiangcheng for less than a day, Chen Xin put on the mask he snatched from the old cat, and quickly changed his appearance.
This brand-new face also has a legal identity, and the ID card produced by Gang Bian can even directly check the relevant file information on the internal website of the Ministry of Public Security.
Afterwards, Chen Xin boarded a high-speed train bound for the central inland province and got off at an unknown county-level city.
Then Chen Xin rented a two-bedroom apartment with his new identity, and spent money to buy 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 once predicted by Mendeleev is mainly used in the electronics industry and communication fields. Its compound gallium arsenide is a very important second-generation semiconductor, and it is also the main raw material for Chen Xin to manufacture phased array radar t/r components.
Historically, gallium arsenide entered the practical stage in 1964.
Gallium arsenide can be made into a semi-insulating high-resistance material whose resistivity is more than 3 orders of magnitude higher than that of silicon and germanium, and is used to make integrated circuit substrates, infrared detectors, gamma photon detectors, etc.
Because its electron mobility is 5 to 6 times larger than that of silicon, it has been widely used in the manufacture of microwave devices and high-speed digital circuits.
Semiconductor devices made of gallium arsenide have the advantages of high frequency, high temperature, 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 magnification of the crystal triode made of it is small, and the thermal conductivity is poor, so it is not suitable for making high-power devices.
Therefore, for the t/r components of the radar, the defect of the low power of the gallium arsenide device appears.
At this time, the new generation of semiconductor material gallium nitride began to enter the attention of scientists from all over the world.
Gallium nitride is a semiconductor with a large bandgap width, which belongs to the so-called wide bandgap semiconductors.It is an excellent material for microwave power transistors and 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. It is a new type of semiconductor material for the development of microelectronic devices and optoelectronic devices. The third generation of semiconductor materials after si semiconductor materials, second-generation gaas, and inp compound semiconductor materials.
It has properties such as wide direct band gap, strong atomic bond, high thermal conductivity, good chemical stability (hardly corroded by any acid) and strong radiation resistance. It is used in optoelectronics, high-temperature and high-power devices and The application of high-frequency microwave devices has broad prospects.
For the military in the information age, the importance of this material is even more prominent.
Not long ago, there was news from Chaoda that Raytheon Corporation of the United States received an honor from the Office of the Secretary of Defense of the United States in recognition of its achievements in participating in the competition for gallium nitride (gan) manufacturing improvement projects.
In the United States, 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 come soon.
Of course, for Chen Xin and Gang Yan, it is not a problem at all to provide the military with t/r components made of gallium nitride on a large scale, and it is even much simpler than gallium arsenide. (To be continued.)
At first, Chen Yuanliang, the mayor of Jiangcheng City, was a little hesitant about Xinghuan Group's proposal.Although this group holds 60.00% of Cybertron's shares, the other party said that they would buy the entire Wujiang Industrial Park as much as 7.6 square kilometers of land and build a sci-fi film and television city.
