摘要：

This is a study of n-type PbTe films produced by deposition from gas-dynamic vapor flows onto glass substrates. It is found that short-term steady heating of these films at 300-400A degrees C in air causes significant changes in their spectral and structural properties because of competition between an increased concentration of deformation defects owing to mismatch of the coefficients of linear thermal expansion of the film and substrate and the healing of these defects.
