As China started late in the third-generation semiconductor materials related research field, it still faces difficulties in the independent preparation of materials. At the same time, China's attention to basic material issues is not enough; once the input and support are not enough, relevant talents will be difficult to attract, and the problem of talent team construction will gradually become a bottleneck for development.
In Beijing, where night falls, if you have the opportunity to pass the North Fourth Ring Road by car, you will be attracted by the radiant, colorful nests and water cubes, and you can't help but stop and enjoy.
Behind these Ambilight buildings, the main benefits of semiconductor lighting technology.
Unfortunately, the water cube 440,000 sets of LED lighting equipment, the Bird's Nest about 258,000 sets of LED lighting equipment are purchased from the United States Cree (CREE) company, it is difficult to "made".
The demand for MOCVD systems is growing, and almost all of China is dependent on imports.
In fact, with the third-generation semiconductor materials becoming the frontier and hotspot of global semiconductor research, China is catching up with key research fields such as semiconductor materials, such as light-emitting devices and microwave power devices, and even start trial production and trial use. However, compared with foreign counterparts, The gap still exists.
