锑化铟单晶的小平面生长及孪晶

采用切克劳斯基技术,观察了按不同晶向从熔态生长InSb单晶时固液界面的形貌。实验表明,结晶面上{111}小平面的发展和性质与单晶体的外形及孪晶的形成有着密切的关系,采用一个闪锌矿结构的{1ll}面八面协及双八面体模型能成功地解释各种实验现象。 关键词：

ON THE FACETS AND TWIN FORMATION IN THE GROWTH OF InSb SINGLE CRYSTALS

The observations of solid-liquid interface morphology of InSb single crystals pulled by using various oriented seeds is described. Experimental results indicate that the external forms of crystals as well as the formation of growth twin are closely related to the development and properties of {111} facets on the solid growth surface. The various experimental phenomena can all be interpreted successfully according to a {111} plane octahedron or two-octahedron model of the zinc-blende structure.
