Terahertz Radiation Detection by Field Effect Transistor in Magnetic Field
, 2009 We report on terahertz radiation detection with InGaAs/InAlAs Field Effect Transistors in quantizing magnetic field. The photovoltaic detection signal is investigated at 4.2 K as a function of the gate voltage and magnetic field.

Fast detector of the ellipticity of infrared and terahertz radiation based on HgTe quantum well structures [PDF]
, 2008 We report a fast, room temperature detection scheme for the polarization ellipticity of laser radiation, with a bandwidth that stretches from the infrared to the terahertz range. The device consists of two elements, one in front of the other, that detect

Terahertz radiation in ophthalmology (review)
Acta Biomedica Scientifica, 2021 Terahertz (THz) radiation is one of the new, intensively studied interdisciplinary fi elds of scientifi c knowledge, including medicine, in the fi rst decades of the 21st century. At the beginning of this article (review), in a brief form, the basic statements on THz radiation, the main parameters and properties are presented; the modern THz ...

Terahertz amplifiers based on gain reflectivity in cuprate superconductors
Physical Review Research, 2022 We demonstrate that parametric driving of suitable collective modes in cuprate superconductors results in a reflectivity R>1 for frequencies in the low terahertz regime.

Terahertz Radiation Effects and Biological Applications
Journal of Infrared, Millimeter, and Terahertz Waves, 2009 We present a brief overview of the literature on biological applications and experimental data on the effects of THz radiation. The region of the electromagnetic spectrum from 0.1 to 10 THz is a frontier area for research in physics, chemistry, biology, materials science and medicine. This area has recently begun to be filled by a variety of sources of

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics
Advanced Functional Materials, EarlyView.Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Investigation of terahertz radiation influence on rat glial cells.
Biomedical Optics Express, 2017 We studied an influence of continuous terahertz (THz) radiation (0.12 - 0.18 THz, average power density of 3.2 mW/cm2) on a rat glial cell line. A dose-dependent cytotoxic effect of THz radiation is demonstrated.
