In this roadmap article, we have focused on the most recent advances in terahertz (THz)
imaging with particular attention paid to the optimization and miniaturization of the THz …

Bibliometric data set the scene by illustrating the growth of terahertz work and the present
interest in terahertz science and technology. After locating terahertz sources within the …

Resonant frequencies of the two-dimensional plasma in FETs increase with the reduction of
the channel dimensions and can reach the THz range for sub-micron gate lengths …

Recently, the technology of terahertz (THz) waves, which have been called undeveloped
electromagnetic waves, has been making remarkable progress. In addition to the …

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 …

We report on room temperature terahertz generation by a submicron size AlGaN/GaN-based
high electron mobility transistors. The emission peak is found to be tunable by the gate …

We present a comprehensive theory of the Dyakonov-Shur (DS) plasma instability in current-
biased graphene transistors. Using the hydrodynamic approach, we derive equations …

Nanometer size field effect transistors can operate as efficient resonant or broadband
terahertz detectors, mixers, phase shifters and frequency multipliers at frequencies far …

We identify a possible mechanism of the plasmon instabilities in periodically gated two-
dimensional electron systems with a modulated electron density (plasmonic crystals) under …

We experimentally demonstrate that above 300 GHz, the plasmonic phase shifter can
operate at up to room temperature. We investigate the temperature-dependent behavior of …
