Abstract

original image

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.
