Energy dissipation in multifrequency atomic force microscopy

Correction to "Energy dissipation in multifrequency atomic force microscopy"

In the section "Energy dissipation" of the above manuscript, there is a typesetting error in the mathematical expressions after Equation 5. The correct form must be: The energy balance of each decaying mode obtained from Equation 4 in the time window 0 < t < τ = 200 μs (see Figure 1) can be written as where i is the index of the mode, ΔK i = 1/2 m eq (v i (0) 2 − v i (τ) 2) is the variation of ...

Anharmonicity in multifrequency atomic force microscopy

In multifrequency atomic force microscopy higher eigenmodes are externally excited to enhance resolution and contrast while simultaneously increasing the number of experimental observables with the use of gentle forces. Here, the implications of externally exciting multiple frequencies are discussed in terms of cantilever anharmonicity, fundamental period and the onset of subharmonic and superh...

Phase contrast and operation regimes in multifrequency atomic force microscopy

Energy dissipation in atomic force microscopy and atomic loss processes.

Atomic scale dissipation is of great interest in nanomechanics and atomic manipulation. We present dissipation measurements with a linearized, ultra-small amplitude atomic force microscope which is capable of measuring dissipation at chosen, fixed separations. We show that the dynamic dissipation in the noncontact regime is of the order of a few 10-100 meV per cycle. This dissipation is likely ...
