Metal Oxide Nanowires: Synthesis, Characterization and Device Applications
07 Mar 2006 | Online Presentations | Contributor(s): Jia Grace Lu
Various metal oxide nanowires, such as ZnO, SnO2, Fe2O3, In2O3 and Ga2O3, have been synthesized by chemical vapor deposition method. Their structures and properties are
characterized by TEM, SEM, XRD, AFM, photoluminescence, photoconductance, scanning surface potential microscopy, and electrical transport measurement. By integrating bottom-up
technique with top-down lithographic technique, these nanostructures are used to fabricate a range of electronic and chemical sensing devices. As an example, individual ZnO nanowires are configured as n-channel field effect transistors, and implemented as highly sensitive chemical sensors for detection of NO2, NH3, CO toxic gases.
