Valleytronics researchers fabricate novel 2D material enjoying long-life excitons

The emerging field of valleytronics, which exploits the momentum preference of excited electrons, or excitons, in a variety of optoelectronic devices, is closely tied to the fabrication of novel 2D materials just atoms thick. This month, a group of valleytronics researchers from Central South University in Changsha, China, have developed one such 2D material that […]
