Abstract We present a theory for plasmonic crystal instability in a semiconductor field-effect transistor with a dual grating gate array, designed with strong asymmetry in the elementary cell of this “crystal”. We demonstrate that, under the acti

Circularly polarized electromagnetic wave impinging on a conducting ring generates a circulating DC plasmonic current resulting in an Inverse Faraday Effect in nanorings. We show that a large ring with periodically modulated width on a nanoscale, sma

We present detailed numerical analysis of the Dyakonov–Shur (DS) plasma instability in a DC biased graphene field-effect transistor (FET) with the gate shifted with respect to the middle of the transistor conducting channel. We show that the geomet

The plasmonic field effect transistors structures (TeraFETs) with the varying width allow for modulation of the electron drift velocity while keeping the plasma velocity constant. The constant plasma velocity and variable electron drift velocity lead

In this work, we realized the requisite asymmetric boundary conditions across a plasmonic cavity, which is formed inside the gated region of a high electron mobility transistor (HEMT), to trigger the Dyakonov-Shur plasma wave instability.

Finding compact, inexpensive terahertz sources, detectors, mixers, and other components is the prime issue in ultrahigh-speed electronics. This article proposes using the instability of plasmonic modes driven by a ballistic direct current to generate

In this paper, a graphene-based plasmonic phase modulator for Terahertz band (0.1–10 THz) communication is proposed, modeled and analyzed. The modulator is based on a fixed-length graphene-based plasmonic waveguide, and leverages the possibility to
