Abstract

A method for producing n-type SiC single crystal, including: adding gallium and nitrogen, which is a donor element, for obtaining an n-type semiconductor during crystal growth of SiC single crystal, such that the amount of nitrogen as represented in atm unit is greater than the amount of gallium as represented in atm unit; an n-type SiC single crystal obtained according to this production method; and, a semiconductor device that includes the n-type SiC single crystal.
