In article number 1705190, Jong‐Hyun Ahn, and Hyunmin Kim, and co‐workers report the generation of acoustic phonons triggered by an A‐excitonic resonance in atomically thin molybdenum sulfide (MoS2) crystals with a sub‐micrometer lateral optical resolution using time‐resolved second‐harmonic generation (SHG) microscopy. This approach may pave the way toward new sensing applications involving light‐induced...
Understanding the collaborative behaviors of the excitons and phonons that result from light–matter interactions is important for interpreting and optimizing the underlying fundamental physics at work in devices made from atomically thin materials. In this study, the generation of exciton‐coupled phonon vibration from molybdenum disulfide (MoS2) nanosheets in a pre‐excitonic resonance condition is...
