| Outline of Final Research Achievements |
The objective of this study was to dramatically increase the ability of passive-type THz scanning near-field microscope to deeply study the local phenomena of materials. We designed a multi-color CSIP (Charge-Sensitive Infrared Phototransistor) to detect multiple wavelengths and achieved 3 color detection. In parallel, we have designed and developed a low-temperature (4.2 K) SNOM/STM in the low-temperature cryostat and achieved far-field images and accurate tip control. In addition, we developed nano-thermometry technique from room-temperature objects for further industrial applications.
