Valley polarization for electronic and optoelectronic technologies clarified
Many of today's technologies, such as, solid-state lighting, transistors in computer chips, and batteries in cell phones rely simply on the charge of the electron and how it moves through the material. In certain materials, such as the monolayer transition metal dichalcogenides (TMDs), electrons can be selectively placed into a chosen electronic valley using optical excitation.
