Force Modulation Mode

Overview

MFM mode principle

FMM mode principle

Force modulation mode is a mode of contact AFM. A mechanical oscillation is applied to the tip during the scan. A map of mechanical properties is carried out by measuring the amplitude of oscillation and the offsets of the phase signal.

 

Interest

  • Study of mechanical properties
  • Elastic and viscoelasticity mapping
  • High sensitivity of the phase signals and amplitude
