Low-temperature scanning tunneling microscopy was used to selectively break the NH bond
of a methylaminocarbyne (CNHCH3) molecule on a Pt (111) surface at 4.7 kelvin, leaving …

Interactions with a single-atom tip become important a few angstroms prior to adhesive
contact to a metallic sample. The collapse of the barrier produces a connecting channel; …

The adsorption of organic molecules on solid substrates is a fundamental step in many
important heterogeneous catalytic processes, and is also becoming an increasingly …

We have observed on− off switching of scanning tunneling microscope current flow to silicon
adatoms of the Si (111)-(7× 7) surface that are enclosed within a bistable dimeric corral of …

High harmonic emission occurs when an electron, liberated from a molecule by an incident
intense laser field, gains energy from the field and recombines with the parent molecular ion …

THE study of surface phenomena is in large part dependent on spectroscopic techniques
that are sensitive to only the outermost few layers of the material under consideration. A …

Scanning tunneling microscopy has revolutionized our ability to image, study, and
manipulate solid surfaces on the size scale of atoms. One important limitation of the …

A novel scanning tunneling microscope manipulation scheme for a controlled molecular
transport of weakly adsorbed molecules is demonstrated. Single sexiphenyl molecules …

THE scanning tunnelling microscope (STM) has been used to visualize DNA1 under water2,
under oil3 and in air4–6. Images of single-stranded DNA have shown that submolecular …

GRAPHITE is a popular choice as a substrate for the study of absorption of molecules on
surfaces because of its relatively simple interaction with adsorbates and the ease of …
