One of the most captivating properties of polaritons is their capacity to confine light at the
nanoscale. This confinement is even more extreme in two-dimensional (2D) materials. 2D …

We study terahertz (THz) radiation transmission through grating-gate graphene-based
nanostructures. We report on room-temperature THz radiation amplification stimulated by …

Two-dimensional plasmons were investigated by terahertz time domain spectroscopy
observing experimentally the distinctive minima and inflection points in the transmission …

Ultrasound-aided liquid phase exfoliation (ULPE) of graphene in pure water is environment-
friendly. Two limiting factors of ULPE are the non-uniform thickness of few-layer graphene …

We devised an electronically controllable plasmonic modulator capable of changing the
phase of the transmitted electromagnetic wave. It is based on a well-established GaAs …

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 …

Exact solutions to diffraction problems in wave optics are scarce though strongly demanded
for accurate knowledge of electromagnetic fields in the immediate vicinity of scatterers. Here …

It has been demonstrated that acoustic plasmon resonances (APRs) with mode sizes of a
few nanometers and large momentums can be excited at nanogaps between graphene and …

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 …
