Research topics: Nanotechnology at Terahertz Frequencies
Investigation of the usage of nanotechnology at submillimeter to infrared frequencies for different space-borne and ground-based applications. Developing planar slot antenna coupled room temperature nano-scale Silicon MOS tunnel-diode based infrared detectors. Monolithically integrated planar slot antennas capable of polarization discrimination and very high free-space to detector efficiency are being developed along with high speed Si-tunnel diodes using highly uniform nano-scale fabrication techniques. Exploring carbon nanotube based Schottky diodes for use as terahertz detectors and sensors. Process of developing silicon micromachined nano-scale waveguide and other structures to develop terahertz heterodyne receivers on a chip.
