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-Ag2S-Ag system. Such spontaneous metallization at the Ag-Ag2S interface may play an important role in fast switching of the Ag-Ag2S atomic switch.
