Surface Layers and Thermoelectric Properties of Vapor-Phase Condensation LAST Pb18Ag2-xSbxTe20 on Mica
Journal Title: Фізика і хімія твердого тіла - Year 2015, Vol 16, Issue 1
Abstract
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.
