This paper reviews the state of rapidly emerging terahertz hot-electron nanobolometers
(nano-HEB), which are currently among of the most sensitive radiation power detectors at …

We report on experiments on photoresponse to sub-THz (120 GHz) radiation of Si field-effect
transistors (FETs) with nanometer and submicron gate lengths at 300 K⁠. The observed …

We report on the experiments on resonant photoresponse of the gated two-dimensional
electron gas to the terahertz radiation. The visible-light-induced, metastable increase of the …

Stellar systems are often formed through the collapse of dense molecular clouds which, in
turn, return copious amounts of atomic and molecular material to the interstellar medium. An …

We study the reset dynamics of niobium (Nb) superconducting nanowire single-photon
detectors (SNSPDs) using experimental measurements and numerical simulations. The …

We report a record double sideband noise temperature of 600 K (5 h ν/k B) offered by a NbN
hot-electron bolometer receiver at 2.5 THz. Allowing for standing wave effects, this value …

Superconducting hot-electron bolometers are presently the best performing mixing devices
for the frequency range beyond 1.2 THz, where good-quality superconductor-insulator …

The authors report on the demonstration of room temperature, tunable terahertz detection
obtained by 50 nm gate length Al Ga As∕ In Ga As high electron mobility transistors …

We report on unusual nonlinear dynamics observed in the resonance response of NbN
superconducting microwave resonators. The nonlinear dynamics which occurs at relatively …

The intermediate frequency (IF) characteristics, the frequency dependent IF impedance, and
the mixer conversion gain of a small area Hot Electron Bolometer (HEB) have been …
