Resonant tunnelling diodes (RTDs) exploit quantum tunnelling through a double‐barrier heterostructure to generate and detect electromagnetic waves in the terahertz (THz) band. Their inherent negative ...

Terahertz wireless has long sounded like the next big leap; fast enough to move huge amounts of data with less delay. Yet the hardware has struggled to keep up. A key part, the resonant tunnel diode, ...

Researchers have now succeeded in producing an extremely simple and compact source of terahertz radiation: An oscillator with double resonant-tunneling diodes. Its radiation power significantly ...

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 ...
