Study on the Growth Quartz Ampoule of AgGaS₂

Abstract:

The changes in the growth quartz ampoule of AgGaS₂ are studied. Coating a layer of carbon film on the inner surface of growth quartz ampoule is an effective measure to prevent AgGaS₂ melt conglutinate with quartz ampoule. It can prevent the impurities of quartz ampoule diffuse into the AgGaS₂ melt. The anomalous thermal expansion phenomenon of the AgGaS₂ crystal usually makes the growth quartz ampoule broken, and crystal crack. Double-layer quartz ampoule can solve the problem. High-quality and large-size AgGaS₂ single crystal is obtained by using carbon coated and double-layer growth quartz ampoule. These methods are simple and effective.
