Abstract
The elastic response of molecular organic materials to external mechanical nanoindentations in the nano- and low micronewton force range can be characterized using ultrasharp cantilever tips of an Atomic Force Microscope (AFM). Because clear distinction between elastic and plastic deformation is achieved, the maximal accumulated elastic energy can be directly determined from the force vs. penetration curves, giving an estimate of the characteristic energies of the materials.
