Abstract: Photoemitted electrons reveal large-momentum (“dark”) excitons in monolayer WSe2 Two-dimensional (2D) semiconductors, such as transition-metal dichalcogenides, may enable new optoelectronic technologies (1). The optical excitation in these atomically thin materials creates tightly bound excitons composed… read more here.
