- Abstract
- We demonstrated a nonvolatile memory fabricated with the sandwich device structure of Al/Au nano-crystals embedded in the PVK/Al. The bi-stable conduction switching characteristic (Ion/Ioff ratio) was >1×102, depending on Au nano-crystal size. The size and distribution of Au nano-crystals were determined by the inserted Au-layer thickness between PVK layers. The size of Au nano-crystals increased with the inserted Au-layer thickness. The uniform distribution of isolated Au nano-crystals was obtained with 5 nm of the inserted Au-layer thickness.
