Germanium: semiconductor properties

THIS paper is designed to be a concise review of the semiconductor properties of germanium. The emphasis will be on those properties of particular interest to those concerned with infrared radiation, As such, some topics will be emphasized, possibly at the expense of others. It is hoped that this article will still be of some interest to the general reader. Germanium has been studied more, in both breadth and depth, than any other semiconductor. The pertinent literature is enormous. Therefore this article will be, in the interests of maintaining a manageable size, essentially a “review of reviews”. It will not, of necessity, attempt to treat its topic exhaustively. Basic data and phenomena will be stressed. Details, if not described, will be referenced in a manner designed to provide the maximum information with a minimum of searching of the literature. In this spirit, no attempt will be made to cite exhaustively the work in a given field. The convenience of the reader will be the prime consideration.
