Summary Of Silicon Carbide Materials And Applications

The 21st century is an era of explosive information technology, and in the rapid development of information technology, it is inevitable that it cannot do without the rapid development of semiconductor materials. The development of semiconductor materials and devices will inevitably trigger a new industrial and technological revolution.
The third-generation semiconductor materials, represented by SiC and GaN, have broad applications in short wavelength lasers, white light emitting diodes, high-frequency high-power devices, and are currently a hot direction for the development of semiconductor industry technology.
Silicon carbide power devices can not only be widely used in traditional industrial fields such as DC and AC transmission, uninterrupted power supply, industrial motors, but also have broad potential markets in new energy vehicles, solar photovoltaic, wind power generation, and other fields.
Compared with the first generation semiconductor material Si and the second generation semiconductor material GaAs, silicon carbide has better physical and chemical properties, including high thermal conductivity, high hardness, chemical corrosion resistance, high temperature resistance, and transparency to light waves.
The wide bandgap semiconductor power device represented by silicon carbide is currently one of the fastest developing power semiconductor devices in the field of power electronics.
The excellent thermal and radiation resistance properties of silicon carbide materials also make it one of the preferred materials for preparing ultraviolet photodetectors.
In addition, silicon carbide based sensors can compensate for the performance defects of Si based sensors in harsh environments such as high temperature and high pressure, thus having a wider application space
Silicon carbide power devices can double the power, temperature, frequency, radiation resistance, efficiency, and reliability of power electronic systems, resulting in a significant reduction in volume, weight, and cost.
