Reorganization energy upon charging a single molecule on an insulator measured by atomic force microscopy.
Shadi Fatayer,Bruno Schuler,Bruno Schuler,Wolfram Steurer,Ivan Scivetti,Ivan Scivetti,Jascha Repp,Leo Gross,Mats Persson,Mats Persson,Gerhard Meyer +10 more
TL;DR: The approach presents a route to perform tunnelling spectroscopy of single adsorbates on insulating substrates and provides insight into single-electron intermolecular transport.

Charge-State-Dependent Diffusion of Individual Gold Adatoms on Ionic Thin NaCl Films
TL;DR: It is shown that the diffusion of gold adatoms on NaCl thin films depends critically on their charge state, and surprisingly, the anionic species has a lower diffusion barrier than the neutral one.
Local thickness determination of thin insulator films via localized states
TL;DR: In this paper, the lifetime of localized states below the conduction band was measured using scanning tunneling microscopy to determine the local thickness of thin insulating films using thin NaCl films grown on Cu(111).

Damping by sequentially tunneling electrons
TL;DR: In this article, a model for the sequential tunneling of electrons through a single chlorine vacancy on a multilayer NaCl film on Cu(100) in the junction of a non-contact atomic force microscope with a conductive tip can lead to a negative damping of the cantilever.

Toggling the Local Electric Field with an Embedded Adatom Switch.
Wolfram Steurer,Bruno Schuler,Niko Pavliček,Leo Gross,Ivan Scivetti,Mats Persson,Gerhard Meyer +6 more
TL;DR: It is shown that Au(+) on NaCl films adsorbs in an embedded, slightly off-centered Cl-Cl bridge position and can be switched between two equivalent mirror-symmetric configurations using the attractive force exerted by a scanning probe tip, suggesting that Au (+) can be used to toggle the local electrostatic field.
