Dzundza B. Influence of inter-phase boundaries on charge carriers scattering mechanisms in lead chalkogenide films

There are executed the divide contribution of different charge carriers scattering mechanisms in the kinetic phenomena of lead chalkogenide thin films of different structural completeness on the basis of complex experimental researches and theoretical calculations. The rules in the directed heterogeneities of the profiles of electric parameters both in annealing in vacuum and oxygen atmosphere, and grown lead chalkogenide films are define and determine. Within the framework of two-layers Petrits model the kinetic parameters of surface layers are determine. On the base of electrical-technical conductive of poly-crystalline films model there are set the rules of time-dependence of the change of crystalline linear size in PbTe films and transport phenomena mechanisms by inter-grain boundaries that relation on thermal-electron emission.
