ABSTRACT:
A semiconductor heterojunction structure comprising a p-type diamond layer and an n-type cubic boron nitride layer on a surface of said p-type diamond layer. Such heterojunction structure is useful for a semiconductor device such as a diode, a transistor, a laser and a rectifier, particularly an element which emits light from blue light to ultraviolet light.
