From Physical Principles to ML-Ready Representations: A Unified Framework for Scanning Tunneling Microscopy

Scanning tunneling microscopy (STM) enables atomic-resolution imaging, but quantitative interpretation remains difficult because tunneling current depends nonlinearly on both surface geometry and electronic structure. We propose a physics-informed representation based on bond valence and tip-height deviation from the...

Thermally and electronically triggered hydrogen shift within a CHCH2 species via surface-assisted hydrogen tunneling

Hydrogen shift along carbon skeletons plays a key role in isomerization and rearrangement reactions in organic synthesis and hydrocarbon catalysis. Here, we demonstrate precise control over hydrogen shift within a bistable CHCH2 species formed on a Cu(110) surface, using a single-molecule approach via scanning tunnelin...
