Abstract
The oxygen adsorption and desorption on the CdZnTe(111)B-(2×2) surface were studied with synchrotron radiation ultraviolet photoemission spectroscopy (SRUPS) and X-ray photoelectron spectroscopy (XPS). The results show that a surface state of clean CdZnTe(111)B-(2×2) surface appears at 0.5 eV below Fermi level (EF), which disappears after the oxygen exposure, and shows again after annealing in UHV. The surface work function of CdZnTe(111)B-(2×2) decreases after the oxygen exposure, and futher reduces after annealing.
