摘要：
Angle-resolved photoelectron spectra are reported along the GAMMA-YBAR and YMBAR directions in the surface Brillouin zone from the CdTe(110) surface, before and after Cs adsorption. By studying the Cs induced spectral modifications we are able to identify surface states of the clean surface. On the whole, the results support our previous assignments, which were based on other identification criteria. We find, however, that the contamination test provides new important information, particularly in cases where surface derived emission is close to-bulk emission.
