Strong light-matter coupling and room temperature exciton polaritons in atomically-thin WS2 crystals
Monolayer transition metal dichalcogenide crystals (TMDCs) hold great promise for semiconductor optoelectronics because their bound electron-hole pairs (excitons) are stable at room temperature and interact strongly with light. When TMDCs are embedded in an optical microcavity, their excitons can hybridise with cavity photons to form exciton polaritons (polaritons herein), which inherit useful properties from their constituents. For example, the low effective mass inherited from the photonic...[Show more]
