Abstract Modifications of complexes by attachment of anchor groups are widely used to control molecule-surface interactions. This is of importance for the fabrication of (catalytically active) hybrid systems, viz. of surface immobilized molecular cat

Catalytically active complexes adsorbed to noble metal surfaces hold potential for CO2 utilisation. Here, the mechanism of growth of fac-Re(bpy)(CO)3Cl on Ag(001) is shown to begin at well-oriented surface steps, with surface restructuring promoting

Measurement of charge transport in epitaxial graphene is challenging. Here, the authors quantitatively investigate local transport properties of graphene prepared by polymer assisted sublimation growth using scanning tunneling potentiometry and repor

Macroscopic magneto-transport measurements enable investigation of the transport properties of materials in the presence of magnetic fields, yet they do not allow access to atomic scale details. Here, the authors combine scanning tunneling potentiome

We investigate single Ge and Ag impurities buried below a Cu(100) surface using low temperature scanning tunneling microscopy. The interference patterns in the local density of states are surface scattering signatures of the bulk impurities, which re

Understanding the dynamics of bound and free charges and local electric fields on a nanometre scale are important in scanning tunnelling microscopy and nanoscale electronics. Here, the authors present a model system—a metallic tip near a gallium ar

We investigate photocurrents driven by femtosecond laser excitation of a (sub)-nanometer tunnel junction in an ultrahigh vacuum low-temperature scanning tunneling microscope (STM). The optically driven charge transfer is revealed by tip retraction cu

By combining highly resolved Scanning Tunneling Potentiometry with the exceptional sample homogeneity of graphene on SiC epitaxially grown by polymer-assisted sublimation growth, we reveal local variations in the resistance associated with substrate

Nanoconfinement of catalytically active molecules is a powerful strategy to control their chemical activity; however, the atomic-scale mechanisms are challenging to identify. In the present study, the site-specific reactivity of a model rhenium catal

Review of Scientific Instruments
Combining scanning tunneling microscopy (STM) and optical excitation has been a major objective in STM for the last 30 years to study light–matter interactions on the atomic scale. The combination with modern pulsed laser systems even made it possi
