A directed effort toward the development of nanowire devices and circuits is proposed, utilizing the self-assembly of nanowires through the vapor-liquid-solid (VLS) technique. The merit of this work is in the investigation of an additional control mechanism through the use of electrostatic forces to join individual nanowires, and the development of a procedure for epitaxially interconnecting to the nanowires from macroscopic electrodes. Investigations will include nanowire p-n junctions, field effect transistors, light emitting diodes, and heterojunction devices. Using the VLS technique to fabricate nanowire interconnects may also prove a viable method of interfacing to molecular electronic circuits, for the fabrication of scanning probes used in scanning tunneling microscopy, or atomic force microscopy, and for making micro-electromechanical systems (MEMS) such as electrical conductivity probes.
