Outline of Final Research Achievements |
In this study we intend to realize a microscopy technique of STM-induced THz emission. We have developed a room-temperature STM in our passive THz near-field microscope and tried to detect STM emission. We observed some near-field signals probably derived by tunnel current emission. However we could not confirm that the signal origin should be the STM emission because of large background noises. To solve the problem, we should develop a similar STM inside a low-temperature chamber. On the other hand, we have succeeded in fabricating 2-color CSIP detectors in THz region in GaAs/AlGaAs “three” quantum well crystals. This 2-coloer detector opens the door to further promote near-field spectroscopy in THz region.
