TL;DR: In this paper, a far-infrared magnetospectroscopy study of a set of HgTe/Cd quantum wells with different thicknesses from below to above the critical value was performed.

TL;DR: In this article, the authors demonstrate room temperature, tunable terahertz detection obtained by 50nm gate length AlGaAs∕InGaAs high electron mobility transistors (HEMTs).

TL;DR: In this paper, a terahertz wave rectification on nonlinearities related to overdamped plasma oscillations in the transistor channel is presented, and it is shown for the first time that room-temperature direct detection with modulation bandwidth of up to 8 GHz can be achieved, thus showing that nanometer-sized FETs can be used as valuable detectors in all-solid-state terrahertz wireless communication systems.

TL;DR: In this article, the authors observed visible second-harmonic and ultraviolet thirdharmonic fields generated in reflection from the surface of a two-dimensional triangular GaN/sapphire photonic crystal when the pump radiation resonates with a photonic mode.

TL;DR: In this article, a hydrodynamic model is presented to simulate the excitation by optical beating of plasma waves in nanometric field effect transistors, where the biasing conditions are whatever possible from Ohmic to saturation conditions.
