Quantitative Quantum Relaxometry Framework for Probing Transient Radical-Associated Magnetic Fluctuations under Operando Conditions

Abstract Transient paramagnetic intermediates play central roles in interfacial chemical and biological processes. However, their short lifetimes make dynamic probing difficult. Existing methods typically rely on reporter chemistry or spin adducts, limiting continuous, operando m...

Quantum noise spectroscopy of nanoscale charge defects in silicon carbide at room temperature

The nanoscale charge environment critically influences the performance of semiconductor devices, yet traditional characterization techniques usually lack the spatial resolution to resolve nanoscale charge heterogeneity and identify microscopic noise sources. Here, we address this...
