Study could lead to production of more efficient optoelectronic devices

Publicado em 21 abril 2021
Resonant-tunneling diodes are used in high-frequency oscillators, wave emitters and detectors, logic gates, photodetectors, and optoelectronic circuits. The study was a collaboration between Brazilian and German researchers. 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 of the phenomenon known as “quantum tunneling”. Called [...]
