Abstract:
A method for growing a compound semiconductor, comprising:a first formation step of forming a first group III-V compound layer on a substrate; a second formation step of forming a second group III-V compound layer including nitrogen and at least one group V element other than nitrogen as a group V composition on the substrate over the first group III-V compound layer; a third formation step of forming a third group III-V compound layer directly between and contacting each of the first group III-V compound layer and the second group III-V compound layer; and wherein the second group III-V compound layer and the third group III-V compound layer each include indium as a group III composition, and an indium composition ratio of the third group III-V compound layer is in a range of âˆ’50% to +50% of an indium composition ratio of the second group III-V compound layer.
