This study demonstrates metallophthalocyanines (MPc) quench defect-related photoluminescence in MoS2 monolayers. The MPc complexes stabilize dark, negatively charged defects over luminescent neutral defects via an electrostatic local gating effect.
Significance and Impact
The results suggest attractive routes for photo-luminescent manipulation and could have applications in flexible electronics, sensors, photovoltaics, catalysts, and neuromorphic computing.
- Modeling and experimental results demonstrate the control of defect-based excited-state decay pathways via molecular passivation.
- First-principles computations were performed using Carbon, a high-performance computing cluster in CNM.
