Arrays of heterojunctions of Ag nanowires and amorphous cairbon nanotubes

Arrays of heterojunctions of Ag nanowires and amorphous carbon nanotubes have been synthesized. These heterojunctions have ohmic current-voltage characteristics based on the general characteristics of electronic structures of amorphous semiconductors and may provide a wide base for the design of various ohmic contacts in nanodevices. The Figure shows atomic force microscopy characterizations of a nanowire-nanotube array.
