Single crystal germanium nanowires cobalt, cobalt germanium nanowire structure, and a method of manufacturing the same

摘要

Provided is a single-crystalline CoxGe1-x nanowire having x of at least 0.01 to less than 0.99, a germanium cobalt nanowire structure having a vertical alignment to the substrate and provided in the cathode of the electric field display and a method of fabricating them using the gas-phase transfer method. By providing the nanowire which uses the graphene or the highly ordered pyrolytic graphite as the substrate and has a vertical alignment to the substrate and uniform size and high density, it is possible to use the germanium cobalt nanowire as a field emission emitter and uses the substrate having the germanium cobalt nanowire formed as a cathode transparent electrode of the field emission display.
