Nanowire phase change memory (PCM) technologies: principles, fabrication and characterization techniques

M. Longo,    National Research Council, Italy

Abstract:

This chapter reviews the various strategies for scaling down phase change materials to improve device performance. It reviews the advantages of phase change nanowires (PC-NWs), top-down and bottom-up fabrication processes and characterisation techniques; technological aspects are also considered. Special focus is placed on the self-assembly of NWs by the vapour-liquid-solid mechanisms, including metalorganic chemical vapour deposition. The compositional and structural analysis of NWs is reviewed.
