Microscopic nanomechanical dissipation in gallium arsenide resonators [PDF]

, 2018
We report on a systematic study of nanomechanical dissipation in high-frequency (approximatively 300 MHz) gallium arsenide optomechanical disk resonators, in conditions where clamping and fluidic losses are negligible.

Study on the AFM Force Curve Common Errors and Their Effects on the Calculated Nanomechanical Properties of Materials

Journal of Engineering, 2016
The atomic force microscope (AFM) force curve has been widely used for determining the mechanical properties of materials due to its high resolution, whereby very low (piconewton) forces and distances as small as nanometers can be measured.

Correction of height-fluctuation-induced systematic errors in polymers by AFM-based nanomechanical measurements

Polymer Testing, 2021
AFM-based nanomechanical measurements are powerful tools for the characterization of polymer composites. However, a flat surface of the samples is usually required, which restricts the wide applications of nanomechanical measurements.
