Abstract
A silicon carbide single crystal has a positive correlation between a temperature and an electric resistivity in a range from room temperature to 400° C., has an electric resistivity of at least 1×10Ω·cm in the range from room temperature to 400° C., exhibits electric conduction by holes while no significant electric conduction properties by electrons are observed regarding electric conduction at room temperature, and has a concentration of a transition element of 1×10/cmor less.
