Abstract

This paper presents fabrication and characterization of a quantum dot-based floating gate nonvolatile memory device with site-specific self-assembly of germanium oxide-cladded germanium (GeOx-Ge) quantum dots on SiO2 and ZnS/ZnMgS/ZnS (II–VI lattice-matched high-κ dielectric) tunnel insulator material. These monodispersed and individually cladded quantum dots have the potential to store charge uniformly in the floating gate and are well suited for nonvolatile memory applications.
