Surface photovolage spectroscopy (SPS) with stationary illumination and surface voltage barrier height measurements in function of temperature for the ZnTe and Zn₀.₇Mn₀.₃Te single crystals in the temperature range between 120 K and 270 K have been carried out. The contact potential difference has been determined between investigated sample surface and vibrating metal (gold) reference electrode. The measurements were performed in the clean vacuum of 10⁻⁶ Pa. Four groups of the surface states in the ZnTe, and additional one group of surface states connected with presence of Mn⁺² ions in Zn₀.₇Mn₀.₃Te have been found. The energy schemes for the investigated materials are presented.
