DEVELOPMENT OF INJECTION ELECTROLUMINESCENT MATERIALS.
Abstract
Work was continued on the growth of crystals of aluminum phosphide improved as to size and quality. Work was continued on the growth in tin using the transport of AlP in solution via a temperature gradient. Some difficulty was still encountered in pouring the solvent from the crystals after the growth run due to clogging of the sieve. The majority of the larger crystals grown were used for contacting studies in order that electrical measurements might be made. Czochralski solution growth was started. The primary effort was made in obtaining a suitable seed on which to nucleate growth. High strength polycrystalline material was obtained from hot pressing. A crucible had to be designed to prevent the aluminum phosphide from floating on the tin surface. A partially successful run was made and some growth was obtained. This technique holds considerable potential for the growth of bulk crystals. This report describes the sample preparation, Czochralski growth attempts, and initial electrical measurements on the crystals. (Author)
