Abstract

Czochralski법에 의한 ZnWO₄단결정을 [100], [101], [001] 방향으로 성공적으로 성장시켰다. 각 축 방향에 따른 성장조건이 rotation speed, pulling rate, 성장된 결정의 직경 등의 변수를 가지고 조사되어졌다. 성장된 결정의 냉각시 발생되는 균열을 annealing 효과에 의하여 방지할 수 있었다. 성장된 결정의 방위는 Laue back reflection으로 결정하였다. 각 축 방향으로 성장된 결정의 미세구조적 특징이 논하여졌으며, 경도, 열팽창계수 및 유전상수의 물리적 특성이 평가되어졌다.
