Valleytronics in a monolayer semiconductor at room temperature

Thu, 10/24/2019 - 22:21
The basic idea of valleytronics is to pass information through two-dimensional (2D) and other very thin conducting materials using the energy valleys - or energy extrema - in their conduction and valence bands. Information can be transmitted by controlling an electron's association with a valley - a manipulation that can be achieved using electric fields, magnetic fields and circularly polarized light. Researchers now have demonstrated a room-temperature approach to manipulating quantum-information carriers, which is usually volatile at room temperature, in a monolayer WSe2 semiconductor.
