Electrostatic Stabilization of Near-Surface Quantum Sensors via Dielectric Interface Engineering

Atharva Paranjape, Kathrin Küster, Olga Shevstova +6

Control of charge-state stability in near-surface quantum defects is critical for nanoscale sensing, yet remains particularly challenging under ultra-high vacuum (UHV), where surfa…

Probing up-conversion electroluminescence of decoupled porphyrin molecules in a plasmonic nanocavity

Li-Qing Zheng, Fábio J. R. Costa, Abhishek Grewal +6

Molecular triplet states can produce significant phosphorescence and act as a relay state for luminescence, such as in up-conversion processes. While this property makes triplet em…

Single-molecule phosphorescence and intersystem crossing in a coupled exciton-plasmon system

Abhishek Grewal, Hiroshi Imada, Kuniyuki Miwa +6

Scanning the sharp metal tip of a scanning tunneling microscope (STM) over a molecule allows tuning the coupling between the tip plasmon and a molecular fluorescence emitter. This…
