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

Photoluminescence and reflectivity of WS\(_{2}\)/hBN and hBN/WS\(_{2}\)/hBN heterostructures Figure 1 compares the low-temperature photoluminescence (PL) and reflectivity (RC) within an energy range… [+17745 chars]
