Description:
As a raw material for making high-efficiency light-emitting semiconductors, silicon carbide has undergone a lot of experiments and research. In 1923, it was discovered that silicon carbide can produce light when it is powered on. The reason why silicon carbide can emit light is due to indirect recombination through impurity energy levels. It is an indirect bandgap semiconductor material. It is concluded that if you want to change the wavelength of light emission, you can add various impurities to silicon carbide, and the light wave can also cover various colors from red to purple to make a light-emitting diode.
