PRODUCTION METHOD FOR 13 GROUP ELEMENT NITRIDE CRYSTAL

摘要

PROBLEM TO BE SOLVED: To produce a 13 group element nitride crystal excellent in crystallinity such as GaN in the condition with little danger. SOLUTION: The production method for the 13 group element nitride crystal is as follows; a metal and/or a compound containing at least a kind of 13 group elements and two or more moles of an alkali metal amide to the metal and/or the compound containing the 13 group element are heated in an airtight vessel in an inert gas atmosphere. After the alkali metal amide is melted, then cooling down.
