INVESTIGATION OF CARRIER INJECTION ELECTROLUMINESCENCE

Abstract

Injection electroluminescence is the conversion of electrical energy into light energy by way of radiative recombination of electrons and holes which are injected from two separate, ohmic contacts, into the volume of a crystal. Many important applications await the practical availability of injection EL light sources. Since the light source is compact, shock-resistant and cool, it might be suitable for special applications such as laser excitation. The preparation of ZnSe crystals suitable for injection EL is discussed. In order to grow better crystals, several methods were developed for melting selenides and sulfides above atmospheric pressure in selenium or sulfur vapors respectively. A new apparatus for Czochralski pulling of decomposable solids under pressure etrolled zone-sublimation-recrystallization for vapor-phase growth of ZnTe and ZnSe are described. The design and operation of a new vacuum system for epitaxial growth of multiple layers is outlined. (Author)
