The conductivity of silicon carbide

The conductivity of silicon carbide

Industrial silicon carbide is a semiconductor, and its conductivity varies with the type and quantity of impurities introduced into the crystal.
The conductivity of silicon carbide increases rapidly with the increase of electric field intensity, and has the characteristic of non-linear change. This characteristic of silicon carbide is used to make lightning rod valve discs.
The resistivity of silicon carbide changes with temperature, but within a certain range it is opposite to the resistance temperature characteristics of metal.
The conductivity of industrial silicon carbide peaks when the temperature rises to a certain value. If the temperature continues to rise, the conductivity will drop again.
