The coupling between light and collective oscillations of free carriers at metallic surfaces
and nanostructures is at the origin of one of the main fields of nanophotonics: plasmonics …

Efficiently fabricating a cavity that can achieve strong interactions between terahertz waves
and matter would allow researchers to exploit the intrinsic properties due to the long …

Ever increasing demands of data traffic makes the transition to 6G communications in the
300 GHz band inevitable. Short-channel field-effect transistors (FETs) have demonstrated …

Photonic crystals and metamaterials have emerged as two classes of tailorable materials
that enable the precise control of light. Plasmonic crystals, which can be thought of as …

Unique properties of plasmons in two-dimensional electron systems (2DESs) have been
studied for many years. Existing theoretical approaches allow for analytical study of the …

We present a comprehensive theory of the one-dimensional plasmonic crystal formed in the
grating-gated two-dimensional electron gas (2DEG) in semiconductor heterostructures. To …

An alternative approach of using a distributed transmission line analogy for solving transport
equations for ballistic nanostructures is applied for solving the three-dimensional problem of …

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

Field-effect transistors coupled to integrated antennas [terahertz field-effect transistors
(TeraFETs)] are photodetectors being actively developed for the terahertz (THz) frequency …

We demonstrate that the ratchet effect—a radiation-induced direct current in periodically
modulated structures with built-in asymmetry—is dramatically enhanced in the vicinity of the …
