A STUDY OF ELECTROLUMINESCENT CADMIUM SULFIDE DIODES,
Abstract
The purpose of this thesis is to present an experimental description of a number of tellurium-cadmium sulfide heterojunction devices and a theory to explain their mechanism of operation. These devices exhibit electroluminescence when operated at liquid nitrogen temperatures. Liquid emission from a p-n junction was first observed by Lossev, in 1923, in naturally occurring junctions. Since the efficiency for conversion of electric energy into light was very low, these junctions did not seem to be of much importance until the discovery of the p-n junction laser in 1963. Therefore, within the past several years, there has been considerable interest in the phenomenon of p-n junction luminescence which has resulted in numerous investigation of the properties and potential applications of semiconductor-diode light sources. From an application point of view, the fact that luminescent emission is such a basic way of efficiently communicating information to the eye makes it a tool whose utility extends to practically every area of technology.
