Abstract
A compound semiconductor material includes Ga.sub.x Al.sub.1-x N (wherein 0.ltoreq.x.ltoreq.1) containing B and P and having a zinc blend type crystal structure. A compound semiconductor element includes Ga.sub.x Al.sub.1-x N (wherein 0.ltoreq.x.ltoreq.1) layer having a zinc blend type crystal structure. A method of manufacturing a compound semiconductor element includes the step of sequentially forming a BP layer and a Ga.sub.x Al.sub.1-x N (wherein 0.ltoreq.x.ltoreq.1) layer on a substrate so as to form a heterojunction by using a metal organic chemical vapor deposition apparatus having a plurality of reaction regions, and moving the substrate between the plurality of reaction regions.
