This proposal seeks to advance the state-of-the-art in the field of nanowire (NW) research by developing novel device architectures with an emphasis on large-area ("macro-electronic") applications, including: (1) Development of a cost-effective device platform based on NW "nets", with an emphasis on sensor applications; (2) Development of core-multishell heterostructure NWs, with an emphasis on single photon sources; and (3) Development of a cost-effective device platform for flexible electronics based on the growth of NWs on carbon nanotube "mats", with an emphasis on photovoltaic applications. Insight into the electron transport mechanisms in single NWs, bundled NWs, and NW networks will be provided by voltage-, frequency-, and temperature-dependent conductivity studies. In addition, the optical properties of single NWs will be investigated by micro-photoluminescence for applications in photovoltaics, photodetectors, and light sources. Finally, the influence of nanowire structure will be studied by high resolution transmission electron microscopy.
