Fig. 3: The formation mechanism of Ag-rich nanoprecipitates during the SPS process.

a Schematic diagram revealing the possible microscopic reactions in the composite film at different stages of SPS process. b Theoretical models to verify the possible formation mechanism of Ag-rich nanoprecipitates. Blue balls represent Ag atoms and yellow balls represent Se atoms.
