Journal ArticleDOI
Molecules on insulating films: scanning-tunneling microscopy imaging of individual molecular orbitals.
TL;DR: Ultrathin insulating NaCl films have been employed to decouple individual pentacene molecules electronically from the metallic substrate, which allows the inherent electronic structure of the free molecule to be preserved and studied by means of low-temperature scanning-tunneling microscopy.
Journal ArticleDOI
Current-Induced Hydrogen Tautomerization and Conductance Switching of Naphthalocyanine Molecules
TL;DR: A coupling of the switching process so that the charge injection in one molecule induced tautomerization in an adjacent molecule is demonstrated.
Journal ArticleDOI
Controlling the charge state of individual gold adatoms.
TL;DR: The nature and control of individual metal atoms on insulators are of great importance in emerging atomic-scale technologies and this work suggests that this is a common phenomenon for adsorbates on polar insulating films.
Journal ArticleDOI
Tracking the ultrafast motion of a single molecule by femtosecond orbital imaging
TL;DR: It is anticipated that the combination of lightwave electronics and the atomic resolution of the approach will open the door to visualizing ultrafast photochemistry and the operation of molecular electronics on the single-orbital scale.
Journal ArticleDOI
Measuring the Charge State of an Adatom with Noncontact Atomic Force Microscopy

TL;DR: It is shown that a tuning-fork atomic force microscope (AFM) operating in a noncontact mode at cryogenic temperatures can resolve the charge state of gold and silver atoms absorbed on a sodium chloride film.
