The thermoelectric properties of thin films Pb18Ag2-xSbxTe20, obtained by condensation of vapor on the high vacuum on mica substrate are researched. Based on a two-layer model Petrits are founded electrical parameters of surface layers. It is shown that condensates thickness d <1 micron are characterized by improved thermoelectric properties. Keywords: thin films, lead telluride, resistivity, mobility.
