Assembly of Bismuth Clusters into Nanowires Using Etched V-Grooves as Templates

摘要

The cluster assembly method reported here employs V-grooves as templates for nanowire fabrication. This technique allows the formation of contacted electrically conducting nanowires using simple optical lithography and without painstaking manipulation of the clusters. In-vacuum, temperature dependent I(V) measurements were performed on Bi wires with widths &1 mum and lengths 50 mum. The temperature dependent resistance of the Bi wires is explained by the variation in the carrier concentration in Bi with temperature
