Light emission from a scanning tunneling microscope is investigated from Ag (111) surfaces
using tips with a clean metallic apex and a molecule-covered shaft. The measurements are …

Covalently tethering porphyrin-based molecules to an otherwise inert gold substrate allows
them to be imaged in an ambient environment using scanning tunneling microscopy …

The tip-surface region of a scanning tunneling microscope (STM) emits light when the
energy of the tunneling electrons is sufficient to excite luminescent processes. These …

Porphyrins are promising components to be used in molecular electronics due to their rich
electronic/photonic properties. Preparation of supramolecular architectures of porphyrins on …

The controlled manipulation of a physisorbed self-assembled monolayer is demonstrated at
room temperature for the first time. Patterns are drawn in a NiOEP monolayer supported on …

We report on the electron induced intramolecular rotation of a single phenyl ring of an
azobenzene derivative adsorbed on a Au (111) surface using a low-temperature scanning …

The bistability in the position of the two hydrogen atoms in the inner cavity of single free-
base naphthalocyanine molecules constitutes a two-level system that was manipulated and …

The scanning tunneling microscope enables atomic-scale measurements of electron
transport through individual molecules. Copper phthalocyanine and magnesium porphine …

Iron tetraphenylporphyrin chloride (FeTPPCl) adsorbed on a Au (111) substrate is
investigated using low-temperature scanning tunneling microscopy. Cl is controllably …

The tip of a scanning tunneling microscope can be chemically modified by transferring a
single molecule from the surface. Such a molecule-terminated tip yields enhanced …
