| Research Abstract |
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.
