Friction. 11:154-164
The tribological properties and scratch resistance of MoS2 bilayer deposited on SiO2/Si substrates prepared via chemical vapor deposition are investigated. Friction force microscopy (FFM) is employed to investigate the friction and wear properties of

Tip-enhanced Raman Spectroscopy (TERS) is a powerful tool for analyzing physical and chemical properties of material at the nanoscale. The most widely used probes for TERS have metal(Au or Ag)-coated AFM tips. However, the durability of metal-coated

We propose a method of producing a tungsten probe with high stiffness for atomic force microscopy (AFM) in order to acquire enhanced phase contrast images and efficiently perform lithography. A tungsten probe with a tip radius between 20nm and 50nm w

The precise measurement of the effective spring constant of a colloidal probe's cantilever is very important for the accurate application of a desired contact load to a sample surface since the contact load is determined by multiplying the effective

As commercial atomic force microscopy (AFM) probes made of Si and Si 3 N 4 have low stiffness, itis difficult to induce sufficient elastic deformation on the surface of a specimen in a tapping mode. Therefore,high-guality phase contrast images can
