Abstract Submitted to the NANOTUBE'02 Workshop:

Semiconductor nanowires can function as active both device elements and interconnects and thus represent promising building blocks for a myriad of electronic and optoelectronic devices. To realize the potential of such structures requires, however, that basic scientific and engineering issues to be addressed, including synthesis, physical properties, hierarchical assembly, and architectural design. This presentation will provide examples focused on each of these, and demonstrate how knowledge from such studies can provide a pathway to integrated systems for computing and other applications. First, our general methodology for predictable and controlled nanowire synthesis will be reviewed. Second, investigations of electrical transport and optical properties of individual nanowires and basic nanowire/nanowire junctions will be described. The development of a range of specific devices based on the fundamental information obtained in these studies will be outlined. Third, architectural design and status report of integrated nanoelectronics systems for computing will be reviewed. Lastly, recent advances in the bottom-up assembly of real-time bio/chem sensors, multi-color nanophotonics sources/detectors and novel modulated nanowire material systems will be described. Challenges and goals for realizing nanotechnologies in the future will be discussed.
