Nanowire based electronics: Challenges and prospects

This review provides a survey of recent progresses in nanowire (NW) electronics. Studies at the single-transistor level have shown that devices based on chemically synthesized nanowires can offer similar or better performance compared to their CMOS counterparts. The ultra-thin body, one-dimensional NW structure further assures that electrical integrity can be preserved even in aggressively scaled devices. Three different approaches have been developed to address the critical device integration issue.
