 The paper presents the results of systematic study of galvanomagnetic properties of
thin films under planar deformation conditions caused by the difference in thermal
expansion of film and substrate materials. Data on the structure and galvanomagnetic properties of block thin films on substrates with different temperature expansion have been obtained. It is found that the deformation of the planar strain leads
to a decrease in the concentration of charge carriers, while the deformation of the
planar compression to an increase. It is revealed that an increase in the coefficient
of thermal expansion of the substrate material leads to an increase in the energy
overlap of the conduction band and the valence band. Symmetric arrangement of
the energy extrema of the valence band and the conduction band relative to the
Fermi level for thin films of Bi95Sb5 composition is found.
