勾形磁场下重力水平和温度梯度对CdZnTe分离结晶生长的影响
Effects of Gravity Level and Temperature Gradient on CdZnTe Detached Solidification Growth under Cusp Magnetic Field
摘要
Abstract
In order to clarify the effects of parameters on the growth quality of CdZnTe crystal in a cusp magnetic field, the global simulation analyses for heat and momentum transfers in a crucible was carried out using a finite-element method. The effects of gravity level, temperature gradient at different magnetic field intensifies on the CdZnTe crystal growth were analyzed. The results showed that the gravity level had a critical value when the maximum stream function of CdZnTe melt was the minimum and there was the weaket melt flow. The maximum stream function and the melt flow increased with the temperature gradient increasing, resulting in an unstable crystal growth. The melt flow is suppressed by applying a cusp magnetic field, which favors the crystal steady growth and sets stage for the growth of large size CdZnTe crystal on the ground.关键词
