"SURFACE-PROGRAMMED ASSEMBLY" OF NANOTUBE/NANOWIRE-BASED INTEGRATED DEVICES

Abstract

We present a review on recently-developed "surface-programmed assembly" strategy for massive production of nanotube/nanowire-based devices. In this process, surface molecular patterns guide the assembly and alignment of nanotubes/nanowires onto specific locations on solid substrates without relying on external forces. The assembled structures were further utilized to fabricate functional devices such as field effect transistors and sensors. Control experiments provided us rich scientific insights including "sliding kinetics" and "lens effect" during the assembly process. Since this method does not require high-temperature processing steps or unconventional fabrication facilities, it is readily available to conventional device industry and may open up new nanodevice industry based on carbon nanotubes and nanowires.
