Annotation Thin polycrystalline films based on PbSnAgTe (LATT) compounds on mica-muscovite substrates are obtained. The dependences of conductivity, mobility of current carriers and specific thermoelectric power on temperature for these condensates are investigated. It is established that the mechanisms of transport of carriers on the intergrain boundaries dominate at low temperatures, and at higher temperatures the charge transport is determined by the volume of grain. The predominant scattering mechanism at higher temperatures is scattering on acoustic phonons.
