Thermal Stress in GaAs Crystal Grown by Liquid Encapsulant Float-zone Method
摘要
Abstract
The thermal stress calculation for a 3 inch diameter gallium arsenide crystal grown by liquid encapsulation full floating zone(LEFZ) method under microgravity has been conducted by using the finite element numerical method. The crystal is assumed to be in a pseudo-steady axisymmetric state and to behave as isotropic linearly elastic body. The effect of the thickness of the encapsulant and the rotation rate of crystal and feed rod on the thermal stress is analyzed.关键词
