Abstrakt: The Bi(TeSe) solid solutions thin films are produced by 'hot wall' thermal evaporation in vacuum. From the data of X-ray diffraction studies, atomic-force microscopy of the surface relief, and Raman spectroscopy, it is established that vacuum thermal annealing at a temperature of 200°C for 1 h substantially increases the degree of film crystallization. The laser radiation excitation power optimal for studies of the Raman spectra of the Bi(TeSe) films is determined. [ABSTRACT FROM AUTHOR]
