Abstract
Abstract A class of intermetallic compound contact materials for III-V semiconductors is obtained by depositing successively and concurrently a thin film of a transition metal and a Group III metal upon the semiconductor and annealing the resultant structure, so resulting in the formation of a monocrystalline intermetallic contact. The contacts are stable at temperatures ranging from 600 DEG -900 DEG C. and may be fabricated by conventional vacuum deposition.
