M. Labardi et al., DYNAMICAL FRICTION COEFFICIENT MAPS USING A SCANNING FORCE AND FRICTION MICROSCOPE, Applied physics. A, Solids and surfaces, 59(1), 1994, pp. 3-10
A novel method to analyze and to distinguish the non-dissipative compo
nent from the dissipative frictional component of the lateral force in
a Scanning Force and Friction Microscope (SFFM) is worked out and app
lied to images acquired on various samples. We have determined the twi
sting spring constants of the cantilevers by computer statical analysi
s, since they are essential for the quantitative determination but are
not provided by the manufacturer. Quantitative results for the mu(D)
dynamical friction coefficient images are reported. Comparison with th
e forward-backward lateral force image subtraction model is made.
