Presented paper is devoted to studying the methods to prepare epitaxial films
of (PbX)₁₋x(Sm₂X₃)x − (X – S, Se, Te; x = 0.04) semiconductors and to examine the
Hall mobility of charge carriers in these films. It is revealed that the derived dependences
μH (T) for the samples on values of the exponential coefficient ν = 1.7-2.8 testify the
temperature course of mobility in the majority of samples and can be explained via the
dispersion of acoustic oscillations in the lattice and presence of a temperature
dependence on the effective mass.
