Method of producing crystals of nitrides of group 13 elements and melt compositions

摘要

It is provided a method of producing a crystal of a nitride of a group 13 element in a melt by flux method. The melt is generated by heating a composition including a material for the group 13 element, a material for at least one of an alkali metal and an alkaline earth metal and a liquid material for germanium. Upon producing a crystal of a nitride of a group 13 element in a melt by flux method, it is thereby possible to reduce in-plane distribution of a property such as carrier density of the thus obtained crystal of a nitride of a group 13 element.

1. A method of producing a crystal of a nitride of a group 13 element in a melt by flux method, the method comprising the step of:
heating a composition comprising a material for said group 13 element, a material for at least one of an alkali metal and an alkaline earth metal and a liquid material for germanium to generate said melt, wherein said liquid material for germanium is liquid at 25° C. under atmospheric pressure.
