On the Tapping Mode Measurement for Young’s Modulus of Nanocrystalline Metal Coatings

On the Tapping Mode Measurement for Young’s Modulus of Nanocrystalline Metal Coatings

Young’s modulus of nanocrystalline metal coatings is measured using the oscillating, that is, tapping, mode of a cantilever with a diamond tip. The resonant frequency of the cantilever changes when the diamond tip comes in contact with a sample surface. A Hertz-contact-based model is further develop...
