Abstract
Abstract The present invention is concerned with a new metallic modified material of intermetallic compound, which has the same chemical composition as an intermetallic compound semi-conductor with a zincblende-type or wurtzite-type crystalline structure and further has a rocksalt-type crystalline structure and which is stable at room temperature under atmospheric pressure to a high pressure.
