| Research Abstract |
The wavelength region from mid-to far-Infrared(30-200μm) gets a lot of attention in the field of astronomy. The goal of this research is to develop a high-sensitive THz detector. By using the MBE(Molecular Beam Epitaxy) technology, I addressed the development of BIB-type Ge detectors that have high sensitivity in mid-to-far-infrared(1.5-10 THz). There are two big issues to develop the detectors ; fabrication of(1) an ultra-pure Ge thin layer on an active layer and of(2) a high performance transparent electrode. For the first time, their bottlenecks are overcome with the MBE technology.
