Study, Design and Fabricate a Cold Crucible System

Abstract

The objective of this program is to conduct a study, design and fabricate a cold crucible system for the synthesis and Czochralski crystal growth of refractory semiconductors and oxides. During the first 6 months a theoretical analysis of the cold crucible relating the properties of the material to the electrical characteristics of the cold crucible has been essentially completed. The thermal analysis, which includes thermal modeling by means of a computer technique, has also been completed. An initial detailed analysis of the RF power control system necessary to provide the desired stability for crystal growth has been completed. The design of a cold crucible assembly suitable for the growth or refractory oxide crystals has been completed. It is a simple, rugged, modular assembly which will be readily adaptable in the future to a controlled-atmosphere furnace system.
