The unambiguous and quantitative modulus and adhesion
data provided by PeakForce QNM can help researchers
answer the critical question of what materials they are
seeing in their topographic images
Additionally, it is now
possible to study the variation and position of mechanical
properties across a surface with ease, and at previously
unattainable resolution
sample since it directly controls
the peak normal force and minimizes the lateral force on
the probe.
Maps of mechanical properties such as Young’s
modulus, adhesion and dissipation are automatically
calculated at the rates and resolutions expected by
advanced SPM users. Since force distance data is analyzed
directly, there is no ambiguity regarding the source of
image contrast, as often occurs in other techniques.
Mechanical property maps are quantitative, low noise,
and can span a very wide range of property values. These
capabilities of PeakForce QNM will provide researchers
with critical material property information to enable better
understanding of their samples at the nanoscale
