Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201501888-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Graphene quantum dots (GQDs) interacting with molybdenum disulfide (MoS₂) monolayers</bold> induce an effective photoexcited charge transfer at the interface. Both the photoluminescence (PL) and valley polarization of this GQDs/MoS₂ heterostructure can be modulated under various doping charge densities. The photon–exciton interaction is used to explain and calculate the heterostructure PL control, and is further applied to the valley‐polarization tuning. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgj2n0rvr9s" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
