We aimed to study novel functionality of nanoscale antennas (nano-antennas), which have effective ability for transmission and reception of light to be applied as small sensors and photo-detectors. We used a technique of photon-detecting scanning tunneling microscope (STM) to characterize their transmission ability. By aiming to achieve advanced functionality, we used metal nanostructures and oxide wires as components of antennas. As an preliminary experiments of novel nano-antenna, we studied fabrication of oxide nanostructures with wide bandgap and characterized their fundamental properties. We found that the single-crystal SnO2 wires showed reversible and nonvolatile resistance modulation as a function of strain under the application of voltage between both ends of the wire. We installed photon-detecting STM to measure light emitting nano-antenna formed by gold nanowires and oxide nanorods. The light emission from Au nano-antenna showed geometry-related features.

我们的目的是研究纳米天线（纳米天线）的新功能，其具有有效的光传输和接收能力，可用作小型传感器和光电探测器。我们利用扫描隧道显微镜（STM）的光子探测技术来表征它们的传输能力。为了实现先进的功能，我们使用金属纳米结构和氧化物线作为天线的组件。作为新型纳米天线的初步实验，我们研究了宽带隙氧化物纳米结构的制备，并对其基本性质进行了表征。我们发现，单晶SnO2线表现出可逆的和非易失性的电阻调制作为应变的函数下施加电压的两端之间的线。我们安装了光子探测STM来测量由金纳米线和氧化物纳米棒组成的发光纳米天线。Au纳米天线的发光具有几何相关的特征。
