The Self-directed Channel Memristor: Operational Dependence on the Metal-Chalcogenide Layer

  • Kristy A. CampbellEmail author


The basic self-directed channel memristor is comprised of five layers of Ge2Se3, SnSe, and an oxidizable metal, Ag. Each layer plays a role in the operation of the memristor, influencing both the electrical and thermal properties of the device. Device operation can be altered by manipulation of these layers through material changes, layer ordering, or layer exclusion. In this chapter the function of the SnSe layer is explored through electrical characterization of several device types in which this metal chalcogenide layer has been altered, either by changing the metal, or replacing Se with Te.
