Atomic force microscopy is based on bending of cantilever by interatomic forces
between atoms at the tip of the scanning cantilever and surface atoms of measured sample.
Objective: The development of ultrafast experimental techniques with femtosecond time resolution is driving the need for deeper theoretical understanding of how intense optical excitation can alter the interatomic forces
, drive atomic motion and effect structural changes in materials.
When an orthodontic wire is deformed, several internal tensions occur, which means that its atoms are spatially dislocated and the interatomic forces
In this model, besides interatomic forces
between atoms, the relative sub-lattices motion is taken into account to describe structural deviations in the bi-atomic lattice.
They measured cell dimensions, composition limits, interatomic forces
, symmetry and distortion of octahedra and tetrahedra in phyllosilicates.
This force can be in the range of interatomic forces
in solids--thus the name "atomic force" microscopy.
These short-range interatomic forces
are always present but not usually noticed, since they operate at atomic scales.
Three features characterize the progress made to date: bigger molecular systems described in atomic detail, longer simulation time scales, and more realistic representations of interatomic forces
