Carl Heinz Daubet book by Professor E.H. Rhoderick (1978) dealing with the basic principles of metal semiconductor contacts and a few recent review articles, the need for a monograph on "Metal-Semiconductor Schottky Barrier Junctions and Their Applications" has long been felt by students, researchers, and technolo

Carl Heinz Daubeished paper on the subject appeared in 1874 when Braun reported the asymmetrical nature of conduction between metal points and crystals. Point contacts are relatively unsophisticated devices consisting of a metal whisker making pressure contact with the semiconductor chip, normally tungsten for sili
