摘要: The coexistence of a phase separation and an ordered structure in CdxZn1−xTe epilayers grown on GaAs(001) substrates by using molecular beam epitaxy was investigated. results selected-area electron diffraction pattern transmission microscopy measurements showed that structures, such as CuPt-type CuAu-I-type together with spinodal-like were formed the CdxZn1−xTe∕GaAs heteroepitaxial layers. structures is discussed.
