Moving atoms on surfaces: Impact of external parameters on required lateral force

Quantifying Force and Energy in Single-Molecule Metalation

“…The manipulation of matter at the atomic scale is one of the most fascinating capabilities of scanning probe methods. Three decades after the first reports of atom manipulation and the controlled movement of single atoms on surfaces with a scanning tunneling microscope (STM), a state-of-the-art atomic force microscope (AFM) can be used to measure the force required to induce atomic motion parallel to the surface. , It is therefore tempting to use an AFM for exploring interactions in chemical reactions at the single-molecule level …”

“…Three decades after the first reports of atom manipulation 1 and the controlled movement of single atoms on surfaces 2 with a scanning tunneling microscope (STM), a state-of-the-art atomic force microscope (AFM) can be used to measure the force required to induce atomic motion parallel to the surface. 3,4 It is therefore tempting to use an AFM for exploring interactions in chemical reactions at the singlemolecule level. 5 An important reaction is the metalation of phthalocyanine (Pc) molecules.…”

Differences in Kondo Splitting of Surface Quantum Systems Induced by Two Distinct Magnetic Tips: A Joint Method of DFT and HEOM

“…This value is in the same order of magnitude as the axial forces reported in related experimental works. 58,59 Under this strong attractive force, the Fe atom detaches from the substrate, jumps to the Co tip, and reverses the magnetic moment of the apex atom at the tip. The value of F then shows a fluctuating downward trend but remains in the negative range.…”

Energy dissipation of a carbon monoxide molecule manipulated using a metallic tip on copper surfaces

“…Molecular manipulation by a probe tip [42][43][44][45][46][47][48][49][50][51][52][53][54] is representative of such research and is an ideal setting to investigate friction. This process is an essential technique for creating fascinating nanostructures on surfaces [55][56][57]; thus, its elemental processes have been intensively investigated [43][44][45].…”

“…In previous studies, the typical scenario was single hopping between two equivalent adsorption sites, as described in the PT model. The lateral force required to move an atom or a molecule on surfaces, i.e., the static frictional force, has also been measured using an AFM technique [46,[48][49][50][51][52][53][54], and the results were interpreted based on this single-hopping scenario. However, discussion of the dynamics and energy dissipation in the manipulation process, i.e., dynamic friction, is lacking.…”
