Physics is the interplay of energy and matter. Energy, in the form of light, interacting with
matter, principally in the solid state, underpins this topical review. The subject is developed …

GaN provides the highest electron saturation velocity, breakdown voltage, operation
temperature, and thus the highest combined frequency-power performance among …

The terahertz (THz) range is the next frontier of electronics and optoelectronics with potential
applications ranging from imaging, space communications, computing, quality control, and …

We report a room-temperature, low-impedance and high-sensitivity terahertz direct detector
based on bilayer graphene field-effect transistor (GFET). Epitaxially grown on silicon …

This paper proposes a CMOS fully integrated 860-GHz terahertz (THz) sensor. The sensor
integrates a single-NMOS THz detector, a low-noise chopper instrumentation amplifier and a …

Aiming at the requirement of passive terahertz imaging, we report a high-sensitivity terahertz
detector based on an antenna-coupled AlGaN/GaN high-electron-mobility transistor (HEMT) …

Field-effect transistors coupled to integrated antennas [terahertz field-effect transistors
(TeraFETs)] are photodetectors being actively developed for the terahertz (THz) frequency …

We report on the modeling and experimental characterization of Si complementary metal-
oxide-silicon (CMOS) detectors of terahertz radiation based on antenna-coupled field-effect …

We review the advances of terahertz (THz) science and technology in biophotonics,
including related challenges and solutions. The main impediment to THz spectroscopy and …

The sensitivity of direct terahertz detectors based on self-mixing of terahertz electromagnetic
waves in field-effect transistors is being improved with noise-equivalent power close to that …
