| Surface photovoltage spectroscopy (SPS) measurements for Cd1-xMnxSe single crystals between 80 and 300 K at the pressure of 10-4 Pa were performed. The Fermi level energy was calculated. From the SPS curves the energy values connected with the electron transitions have been determined. Four types of effects have been stated: energy gap, shallow states close to the conduction band and two energy states connected with the structural defects, the native ones and those related to introduction of manganese into the CdSe matrix. |
