| Research Abstract |
In order to confirm whether STM light is detectable in the THz spectral range, experimental investigations have been carried out. Light emission from the Sb2Te3 sample -W tip gap of a STM was successfully detected in the THz spectral range. This result shows that spectroscopic investigations with atomic spatial resolution in the THz spectral range are indeed possible, because the tunneling electron beam in STM, which excites the STM light emission, is well focused up to the atomic level.
