Abstract

The Ag 2 S thin film is formed by sulfurization of Ag film using H 2 S exposure, followed by structural transformation into FCC and monoclinic phases. Ag/Ag 2 S/Ag device fabricated from the film exhibits artificial synaptic behavior, emulating biological synapse responses for neuromorphic computing.
