Has anybody tried friction measurement by AFM. I have a viscoelastic film on silicon. I would like to characterize the frictional force by AFM. Is viscoelastic properties can also be studied by AFM? Can we correlate the friction force data with viscosity of the film? Because my film becomes more fluidic when it heats up around 60oC. I would like to see how frictional force or viscosity is changing with increasing temperature. Any inputs or papers would be highly appreciable.
