摘      要：Silver selenide thin film is one of the best candidates for thermoelectric *** the previous report,we demonstrated that high-performanced[201]orientedβ-Ag_(2)Se thin films can be prepared by direct metal surface element reaction(DMSER)solution selenization in a really short time at room ***,the underlying mechanism of the fast reaction process were not discussed in ***,based on hard soft acid base(HASB)theory and strong oxidation,we further explored the possible reaction mechanism of the in-situ growth ofβ-Ag_(2)Se thin films as the function of the reaction *** time-dependent experimental results showed that the formation of theβ-Ag_(2)Se on elemental Ag precursor(∼690nm thick)in Se/Na_(2)S precursor solution is in a growth driven mode with no obvious orientation or growth rate selections to the elemental Ag *** investigations provide a prerequisite for the further preparation of thermoelectric materials with excellent properties.
