The Processes of Structure Formation in Condensates SnTe/mica Obtained by Method "Hot Wall"
Journal Title: Фізика і хімія твердого тіла - Year 2014, Vol 15, Issue 2
Abstract
Presented by results of AFM studies and electrical properties of vapor-phase condensates SnTe on fresh chipped (0001) single crystals of muscovite mica at deposition temperature TS = (100-250)°C. Shown that there is a mechanism of nucleation Folmer-Weber implementation stages of the formation of nonequilibrium nanocrystals and their avtocoalescence and crossing over to the rounded shape faceted structures. Established that the defect structure is characterized by twin boundaries and voids created by splice parallel and antiparallel trihedral nanoformations. Discovered increase of the lateral size and height nanokrystals with increasing deposition temperature. Stable p-type conductivity of condensate explained offset the homogeneity of the compound SnTe on the side of tellurium, the value of which depends on the temperature of the substrate.
