Description

Atomic force microscopy (AFM) or scanning force microscopy (SFM) is a very high-resolution type of scanning probe microscopy, with demonstrated resolution on the order of fractions of a nanometer, more than 1000 times better than the optical diffraction limit.

  1. SPMW Nanotube, nanoneedle and nanomeniscus: mechanical and wetting properties of modified AFM tip apex

    0.0 out of 5 stars 

    Online Presentations | 12 Dec 2006 | Contributor(s):: J. P. Aimé

    Among AFM microscopes, Dynamic force microscopes (DFM) are very sensitive to variation of minute forces involved in the interaction between the tip and the surface. However, despite numerous efforts, imaging and probing mechanical properties of soft materials in air and water at the nm scale are...

    Online Presentations | 05 Jan 2007 | Contributor(s):: Arvind Raman

    The field of nonlinear dynamics deals with mathematical techniques to study the nonlinear equations that serve as models of physical systems. The benefits of using nonlinear dynamics concepts to interpret and predict probe oscillations in dynamic AFM [1] are becoming increasingly clear. Nonlinear...

  4. SPMW Mechanisms of atomic friction studied by friction force microscopy

    Online Presentations | 12 Dec 2006 | Contributor(s):: Ernst Meyer

    Force microscopy is a versatile instrument to investigate physical phenomena on surfaces. The first emphasis is on the study of friction on the nanometer-scale, also called nanotribology. It will be shown that atomic-scale stick-slip is relatively well understood, where the dependence on velocity...
