Nanoelectrical analysis of single molecules and atomic-scale materials at the solid/liquid interface Nirmalraj, Peter Thompson, Damien Molina Ontoria, Agustín Sousa, Marilyne Martín, Nazario Gotsmann, Bernd Riel, Heike 547 Atoms Calculations Electronic structure Graphene Interfaces (materials) Molecular dynamics Molecules Scanning tunneling microscopy Vacuum applications Química orgánica (Química) 2306 Química Orgánica Evaluating the built-in functionality of nanomaterials under practical conditions is central for their proposed integration as active components in next-generation electronics. Low-dimensional materials from single atoms to molecules have been consistently resolved and manipulated under ultrahigh vacuum at low temperatures. At room temperature, atomic-scale imaging has also been performed by probing materials at the solid/liquid interface. We exploit this electrical interface to develop a robust electronic decoupling platform that provides precise information on molecular energy levels recorded using in situ scanning tunnelling microscopy/spectroscopy with high spatial and energy resolution in a high-density liquid environment. Our experimental findings, supported by ab initio electronic structure calculations and atomic-scale molecular dynamics simulations, reveal direct mapping of single-molecule structure and resonance states at the solid/liquid interface.We further extend this approach to resolve the electronic structure of graphene monolayers at atomic length scales under standard room-temperature operating conditions.
