Abstract
A method for producing a GaN-based crystal includes forming a Zinc-blend type BP crystal layer on a Si substrate; forming an In-containing layer, on the BP crystal layer, with such a thickness as to keep the Zinc-blend type structure; and forming a Zinc-blend type GaN-based crystal layer on the In-containing layer. The In-containing layer is a metallic In layer having a thickness of 4 atom layers or less, an InGaN layer having a thickness of 2 nm or less, an InAl mixture layer having a thickness of 4 atom layers or less and containing Al at 10% or less, or an AlInGaN layer having a thickness of 2 nm or less and containing Al at 10% or less.
