A comprehensive device model considering both spatial distributions of the terahertz field and the field-effect self-mixing factor has been constructed for the first time in the thesis. The author has found that it is the strongly localized terahertz field induced in a small fraction of the gated electron channel that plays an important role in the high responsivity. An AlGaN/GaN-based high-electron-mobility transistor with a 2-micron-sized gate and integrated dipole antennas has been developed and can offer a noise-equivalent power as low as 40 pW/Hz1/2 at 900 GHz. By further reducing the gate length down to 0.2 micron, a noise-equivalent power of 6 pW/Hz1/2 has been achieved. This thesis provides detailed experimental techniques and device simulation for revealing the self-mixing mechanism including a scanning probe technique for evaluating the effectiveness of terahertz antennas. As such, the thesis could be served as a valuable introduction towards further development of high-sensitivity field-effect terahertz detectors for practical applications.

Electromagnetic waves within a terahertz frequency range are becoming critical to investigating molecules, materials, and possible applications that are operated by both visible light and infrared rays. This book discusses sensing, imaging, and optoelectronic technologies of terahertz electromagnetic waves in theory and experiments. Most terahertz technologies can be explained by fundamentals of applied physics that have been demonstrated in other spectral ranges. However, the optoelectronic technology and corresponding configurations of imaging and sensing techniques are so special for various terahertz material polarization waves, which are excited in solid-state media by high-peak power lasers and waveguide transportation. Thus, this book also specifies terahertz parameters and available technologies.

This book highlights reviews, perspectives, and original research that contribute to the advanced interdisciplinary studies of theories, technologies, and strategies on THz sensing, biophysics, communications, and bio-effect research. The terahertz (THz) frequency covers a spectrum important for applications such as body security, non-destructive matter sensing, bio-imaging, and bio-medicine. It overlaps with the characteristic fingerprints of molecular vibrations and rotations (e.g., proteins and DNA) and thus could resonantly interact with various bio-matters. The 2021 Nobel Prize in medicine was granted for the discovery of ion channels of temperature and pressure sensing. The frequency of THz makes it absorbable for bio-effect and modulation of bio-molecules, especially for ion channels. Besides, the high-speed modulation in terahertz is a holy grail for integrated photonics in high-capacity computations. This topic has raised widespread interest in fundamental science and applications for THz. The proceedings are suitable for researchers and students interested in interdisciplinary research at the intersection of electromagnetics, physics, and life sciences.
