Title: Synthesis and nanoscale thermal encoding of phase-change nanowires

Abstract

Low-dimensional phase-change nanostructures provide a valuable research platform for understanding the phase-transition behavior and thermal properties at nanoscale and their potential in achieving superdense data storage. Ge{sub 2}Sb{sub 2}Te{sub 5} nanowires have been grown using a vapor-liquid-solid technique and shown to exhibit distinctive properties that may overcome the present data storage scaling barrier. Local heating of an individual nanowire with a focused electron beam was used to shape a nano-bar-code on a Ge{sub 2}Sb{sub 2}Te{sub 5} nanowire. The data encoding on Ge{sub 2}Sb{sub 2}Te{sub 5} nanowire may promote novel device concepts to implement ultrahigh density, low energy, high speed data storage using phase-change nanomaterials with diverse thermal-programing strategies.
