Abstract

The components of CdZnTe (1 1 1) A and B surface were measured by XPS. The result shows that Te atoms at the A topmost surface are chemically bonded by O atoms, but Te atoms are not at B surface. A new reconstruction structure (sqrt(3) × sqrt(3)) R 30 ° is uncovered for CZT (1 1 1) A surface through low-energy electron diffraction, and is explained in terms of a surface vacancy model. The surface state is measured by Angle-resolved photoemission spectroscopy, which confirms that there are dangling bonds at the reconstructed CZT (1 1 1) A surface.
