Abstract

A method is provided for producing a single crystal body of a group III nitride, comprising the steps of forming a molten flux of a volatile metal in a reaction vessel and causing a growth of a GaN single crystal from the molten flux, wherein the growth is continued while replenishing a compound containing N from a source outside the reaction vessel, and wherein a seed crystal is disposed in the reaction vessel.
