Abstract: A detailed temperature dependence of the energy gap E 0 in the PbSe and PbTe was obtained from the transmittance measurements. A non-linear change of E 0 in the vicinity of the Debye temperature was noticed. An attempt to find an empirical formula describing the experimental dependence E 0 (T) led to the conclusion that the non-linear change can be attributed to the electron interaction with the optical phonons.
