Highly Efficient Exciton Modulation in MoSe2/PdSe2 Heterostructures

Abstract We report a pronounced ∼6-fold enhancement of room-temperature A-exciton emission in a type-I MoSe2/PdSe2 van der Waals heterostructure, yielding a photoluminescence quantum yield of 6%, as compared to ∼1% for as-exfoliated monolayer MoSe2. This unusual enhancement is ac...
