| Abstract: | We report the results of Hall effect and deep-level-transient-spectroscopy measurements onn-type indium selenide samples cleaved from non-intentionally doped material and from chlorine, tin, gallium sulphide or oxygen doped ingots. Some unidentified shallow and deep levels are found. Impurity levels attributed to Cl (310 meV) and to Sn (44 and 120 meV) are also reported. Anomalous degeneracy of electrons at low temperature is discussed. |
