Товщинні залежності термоелектричних параметрів тонких плівок на основі сполук LAST

The thermoelectric properties of thin films based on compounds PbSnAgTe, 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 < 500 nm are characterized by improved thermoelectric properties. Keywords: size effect, thin film, lead telluride, thermoelectric properties.
