We present resonant-tunnelling-diode (RTD) oscillators operating at the fundamental
frequency of 1111 GHz. We show that our RTDs and RTD oscillators have much room for …

The review outlines the basic principles of operation of resonant-tunnelling diodes (RTDs)
and RTD oscillators followed by an overview of their development in the last decades …

In search for possibilities to increase the operating frequencies of resonant-tunneling diodes
(RTDs), we are studying RTDs working in an unusual regime. The collector side of our …

The concept of on-chip double-resonant-tunneling-diode (RTD) patch-antenna oscillator has
the virtues of compactness, simplicity, high isolation from the external circuitry, and …

Historically, the physics, energy spectrum, and wave functions of superlattices have had
different levels of understanding. Unlike the standard approaches, based on theorems for …

We show that the maximum output power of a simple resonant-tunneling-diode (RTD)
oscillator is fundamentally limited by the radiation conductance of its antenna and by a …

We demonstrate an “island” design of on-chip slot-antenna resonant-tunneling-diode (RTD)
oscillators, where the contact nþþ layer is removed everywhere except for a small island …

The frequency band of the electromagnetic spectrum between microwaves and infrared is
nowadays defined as the Terahertz band (1 THz corresponds to 1012 Hz). The development …

The nonlinear response of resonant-tunnelling diodes (RTDs) is analysed theoretically at
high frequencies (HFs), which are far above the diode's tunnel-relaxation-time limit. We …

We develop in this work a qualitative quantum electron transport model, in the strong light-
matter coupling regime under dipole approximation, able to capture polaritonic signatures in …
