Resonant harmonic response in tapping-mode atomic force microscopy
(American Physical Society, 2004)
Higher harmonics in tapping-mode atomic force microscopy offers the potential for imaging and sensing material properties at the nanoscale. The signal level at a given harmonic of the fundamental mode can be enhanced if ...
Power dissipation analysis in tapping-mode atomic force microscopy
(American Physical Society, 2003)
In a tapping-mode atomic force microscope, a power is dissipated in the sample during the imaging process. While the vibrating tip taps on the sample surface, some part of its energy is coupled to the sample. Too much ...
Enhancing higher harmonics of a tapping cantilever by excitation at a submultiple of its resonance frequency
(American Physical Society, 2005-03)
In a tapping-mode atomic force microscope, the frequency spectrum of the oscillating cantilever contains higher harmonics at integer multiples of the excitation frequency. When the cantilever oscillates at its fundamental ...
