Semiconducting Metal Oxide Nanowires
Abstract:
(Host: Professor Jie Liu) Nanowires are of both fundamental and technological interest. They represent the critical components in the potential nanoscale electronic and photonic device applications. In this talk, the vapor-liquid-solid crystal growth mechanism will be briefly introduced for the general synthesis of nanowires of different compositions, sizes, and orientation. Some unique properties including light emission, and thermoelectrics will be discussed. In addition to the recent extensive studies on "single-component" nanowires, of increasing importance is the capability of incorporating different interfaces, heterojunctions as well as controlling doping profiles within individual single crystalline nanowires. I will present our recent research efforts towards superlattice nanowires and other nanostructures with horizontal junctions. The implication of these hetero-junctioned nanowires in light emission and energy conversion will be discussed.
