Abstract

Combining nonequilibrium Green's function technique with density functional theory, electron transport, and structural properties of an Ag atomic switch through Ag₂S have been investigated. We have found that an Ag atomic conductance channel in Ag₂S is generated after structure optimization, resulting in large enhancement of the electron transmission coefficient at the Fermi level and metallic behavior of the Ag-Ag ₂S-Ag system. Such spontaneous metallization at the Ag-Ag ₂S interface may play an important role in fast switching of the Ag-Ag₂S atomic switch.
