METHOD FOR MANUFACTURING GROUP XIII NITRIDE CRYSTAL

摘要

PROBLEM TO BE SOLVED: To easily manufacture a group XIII nitride crystal such as gallium nitride having excellent crystallinity under a low dangerous condition particularly by a solution synthesis. SOLUTION: In this method for manufacturing the group XIII nitride crystal, the group XIII nitride crystal having excellent crystallinity is obtained by heating a metal and/or a compound containing a group XIII element and an alkali metal amide of not less the five fold mol thereof under an ammonia atmosphere to bring the molten alkali metal amide into contact with the metal and/or the compound containing the group XIII element.
