Electronegativity determination of individual surface atoms by atomic force microscopy
Electronegativity is a fundamental concept in chemistry. Despite its importance, the experimental determination has been limited only to ensemble-averaged techniques. Here, we report a methodology to evaluate the electronegativity of individual surface atoms by atomic force microscopy. By measuring bond energies on the surface atoms using different tips, we find characteristic linear relations ...
متن کاملAdsorption geometry determination of single molecules by atomic force microscopy.
We measured the adsorption geometry of single molecules with intramolecular resolution using noncontact atomic force microscopy with functionalized tips. The lateral adsorption position was determined with atomic resolution, adsorption height differences with a precision of 3 pm, and tilts of the molecular plane within 0.2°. The method was applied to five π-conjugated molecules, including three...
متن کاملLateral Manipulation of Single Atoms Using Atomic Force Microscopy
Engineering nanostructures on different surfaces by manipulating single atoms and molecules is an ultimate target in nanotechnology. Since the first time that atoms were individually arranged on a surface [1], the technique has reached a level in which it is possible to build a logic gate based on few molecules [2] or to set the initial stage of wiring a molecule [3]. Most of these impressive e...
متن کاملManipulation of single atoms by atomic force microscopy as a resonance effect.
Extraction and deposition of single atoms using an atomic force microscope tip is a promising technique for building nanostructures. Previous theoretical models for this technique, based on adiabatic atom motion in either classical or quantum mechanics settings, encountered an apparent difficulty in explaining atom extraction and deposition for the same experimental conditions. We resolve that ...
متن کاملSingle Molecule Force Spectroscopy on Polysaccharides by Atomic Force Microscopy
Recent developments in piconewton instrumentation allow the manipulation of single molecules and measurements of intermolecular as well as intramolecular forces. Dextran filaments linked to a gold surface were probed with the atomic force microscope tip by vertical stretching. At low forces the deformation of dextran was found to be dominated by entropic forces and can be described by the Lange...
