ANOMALOUS IMPURITY SEGREGATION IN InSb SINGLE CRYSTALS
锑化铟单晶中杂质的反常分凝

The impurity distributions on the cross-section of Te-doped and non-doped InSb single crystals are determined by means of Hall technique and mass-spectrum analysis. Results of measurements show clearly that the impurity segregation is anomalous on the facets. These phenomena are discussed in connection with the mechanism of the facet effect. An explicit expression based on thermodynamic considerations is derived and applied to explain the observed anomalous segregation phenomena.
