Drift instabilities in bounded two-dimensional electron systems (2DESs) promise robust
applications in terahertz technology. Until recent years, the severest obstacle for drift …

We analytically investigate the plasmons propagating in a homogeneous two-dimensional
(2D) electron system, along the metal grating in the form of a periodic array of strip-shaped …

Near-gate plasmons are a new type of plasma oscillations emerging in homogeneous two-
dimensional electron systems where a gate provides partial screening of electron-electron …

High-mobility field-effect transistors (FETs) can serve as resonant detectors of terahertz
radiation due to excitation of plasmons in the channel. The modeling of these devices …

Perturbation theory is an indispensable tool in quantum mechanics and electrodynamics
that handles weak effects on particle motion or fields. However, its extension to plasmons …

Despite numerous applications of two-dimensional (2D) plasmons for electromagnetic
energy manipulation at the nanoscale, their quantitative refraction and reflection laws …

Recent experiments in the doped cuprates La 2− x Ba x CuO 4 have revealed the emission
of anomalous terahertz radiation after impulsive optical excitation. Here, we theoretically …

We theoretically demonstrate that dc electron flow across the junction of two-dimensional
electron systems leads to excitation of edge magnetoplasmons. The threshold current for …

We discuss the barrier-injection transit-time (BARITT) diodes and transistors which could be
realized by modern silicon nanotechnology. The main advantage of such kind structures is …

An analytic model of low-dimensional transit-time diodes and transistors for the generation
and detection of THz radiation in a linear approximation with respect to an alternating …
