Researchers observe light emission from intervalley excitons for the first time
Researchers from the University of California, Riverside, has observed light emission intervalley transmissions. The researchers say that this light emission can be used to read valley information from Valleytronics devices in the future.
The researhers observed the phenomenon in monolayer tungsten diselenide (WSe2) - a promising valleytronic material that possesses two valleys with opposite dynamic characteristics in the band structure, and can interact strongly with light.
