The frequency around 1 THz between radio waves and light is called the terahertz band (or submillimeter waveband, far infrared), and has yet to be developed. Light sources and detectors that generate ...

PORTLAND, Ore. — Semiconductor researchers have known since the 1950s that the quantum-confinement effects of tunnel diodes boost circuit speed and current handling while reducing component count and ...

Diodes are widely used electronic devices that act as one-way switches for current. A well-known example is the LED (light-emitting diode), but there is a special class of diodes designed to make use ...

Researchers have invented a new organic polymer tunnel diode -- an electronic component that could one day lead to plastic computer memory and plastic logic circuits on computer chips. Today, computer ...

Assistant Professor Shigehisa Shibayama (right) and first author Shota Torimoto (left), along with the rest of the team, have developed a resonant tunneling diode using only non-toxic Group IV ...

Engineers have designed a new diode that transmits more electricity than any other device of its kind, and the inspiration for it came from technology that is 40 years old. COLUMBUS, Ohio – Engineers ...

Despite being well documented, nonlinearity—its theory and applications—is often viewed as a novelty or strange anomaly. Here, we’ll argue the opposite point of view. Nonlinear and negative ...

In the first part of this series, we took a look at a “toy” negative-differential-resistance circuit made from two ordinary transistors. Although this circuit allows experimentation with ...
