Outline of Final Research Achievements

Terahertz (THz) technologies are expected to be powerfully utilized in a variety of fields including materials science and life science. This research is aimed at the development of nanoscale control of THz evanescent waves and its application to study on nanoscale condensed matter physics. By scanning a nanoscale semiconductor sensor, we have successfully visualized THz radiation associated with electron injection into a semiconductor device. Furthermore, the development of a hybrid of a three-dimensional silicon structure and a metallic film has led to a strong enhancement in THz electric field in a sub-wavelength region and highly sensitive THz sensing of tiny samples.
