Nanowire Optoelectronics

该提案旨在通过开发以大面积（“宏观电子”）应用为重点的新型设备架构来推进纳米线（NW）研究领域的最新技术，包括：(1)开发基于纳米线“网络”的具有成本效益的设备平台，重点是传感器应用；(2)核-多壳异质结构纳米粒子的发展，重点是单光子源；(3)基于碳纳米管“垫”上NWs的生长，开发具有成本效益的柔性电子器件平台，重点是光伏应用。通过电压、频率和温度相关的电导率研究，将深入了解单个NWs、捆绑NWs和NW网络中的电子传递机制。此外，将通过微光致发光研究单个NWs的光学特性，以用于光伏、光电探测器和光源。最后，利用高分辨透射电子显微镜研究纳米线结构的影响。

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.
