Abstract

A heteroepitaxial growth method for gallium nitride yields gallium nitride which contains good quality fine crystals and has excellent optical properties, on a quartz substrate or a silicon substrate. The method comprises a step A of nitriding the surface of the substrate, and a step B of depositing or vapor depositing at least one atom layer of gallium.
