The atomic and electronic structure of CdZnTe (1Â 1Â 1) A surface

From the low-energy electron diffraction (LEED) pattern for clean and smooth CZT (1 1 1) A surface, we can deduce that the original structure of CZT (1 1 1) A have been reconstructed to (111)-(3×3)R30°. The reconstruction can be explained by vacancy model.
