Combining bilayer MoS 2 with different types of quantum dots yields hybrids that exhibit increased light harvesting, interfacial charge transfer and nonradiative energy transfer. Scanning photocurrent microscopy, applied by Chang‐Yong Nam, Mircea Cotlet and co‐workers in article number 1707558 , reveals fast response in CdSe‐MoS 2 hybrids, ideal for photodetector applications. While CdSe‐ZnS‐MoS 2 hybrids show suitability for photovoltaics in the form of enhanced charge carrier generation.
