Physicists’ finding could Revolutionize Information Transmission

Gate Tunable Dark Trions in Monolayer WSe2Physical Review Letters, 2019; 123 (2) DOI: 10.1103/PhysRevLett.123.027401

Team identifies dark trions as the next carrier of quantum information. Move aside, electrons; it’s time to make way for the trion. A research team led by physicists at the University of California, Riverside, has observed, characterized, and controlled dark trions in a semiconductor – ultraclean single-layer tungsten diselenide (WSe2) – a feat that could increase the capacity and alter the form of information transmission.

In a semiconductor, such as WSe2, a trion is a quantum bound state of three charged particles. A negative trion contains two electrons and one hole; a positive trion contains two holes and one electron...
