Upconversion photoluminescence excitation reveals exciton–trion and exciton–biexciton coupling in hBN/WS $$_{2}$$ 2 /hBN van der Waals heterostructures

Abstract Monolayers of transition-metal dichalcogenides with direct band gap located at the binary $$K_{-}/K_{+}$$ K - / K + points of the Brillouin zone are promising materials for applications in opto- and spin-electronics due to strongly enhanced Coulomb interactions and specific spin-valley prop...
