Oscillating mode

A tip vibrating at its resonant frequency sweeps the surface using piezoelectric motors. Laser detection maintains the amplitude of oscillation constant during the measurement. The movements of the vertical piezoelectric motor are recorded to reconstruct the surface. Mapping of mechanical properties is achieved with the offsets of the phase signal. (phase contrast).

Applications

 Materials science
 Semiconductor
 Life science
 Nanostructure
 Polymer

Interests

High sensitivity in phase contrast

AFM oscillating mode preserve surfaces and probes. It is very versatile and adapts to all types of surfaces which are rather soft such as polymer or rather hard such as micro-electronics and metals. The phase shift when the tip touches the surface provides information on mechanical properties such as hardness and elasticity. The finest tips are adapted to the modes oscillating because the contact forces between the tip and sample are particularly low.

Benefits

 Lock-in included
