A method for the rapid synthesis of large quantities of metal oxide nanowires at low temperatures
Additional Document Info
A method for the rapid synthesis of large quantities of metal oxide nanowires at low temperatures was presented. The approach is based upon the control of growth parameters by exposing metal foils to low-pressure, weakly ionized, fully dissociated, and cold oxygen plasma. A niobium foil was exposed to an oxygen plasma for 90 seconds. The surface of the sample after plasma treatment was observed using scanning electron microscopy (SEM). The SEM images revealed interesting structures. The entire surface of the foil was found to be covered with bundles of nanowires with submillimeter lengths.
