Investigation of the physical processes taking place in MIM systems as well as precise determination of the basic parameters of the semiconductor layer (dielectric permittivity and effective electron mass) and of the potential barrier (electron work function) is of great interest. Bulk samples from the Ge- Se-(B,Ga,Tl) ternary system were prepared by direct monotemperature synthesis in evacuated quartz ampoules. Thin films of the system were prepared by vacuum sublimation. The film structure has been investigated by X-ray and electron diffraction, their composition by Auger electron spectroscopy.
