Probes in Scanning Microscopies correspond to the tip radius of curvature, the tip aspect ratio, and the sample height. Although silicon and silicon nitride tips have a somewhat large radius of curvature, low aspect ratio, and limited lifetime due to wear, the widespread use of AFM today is due in large part to the broad availabi

Dynamic Modes of Atomic Force Microscopy the application of dynamic AFM. First, the amplitude-modulation mode (also called the tapping mode) is shown to exhibit an instability, which separates the purely attractive force interaction regime from the attractive–repulsive regime. Second, the self-excitation mode is derived and its experiment

Molecular Recognition Force Microscopy: From Simple Bonds to Complex Energy Landscapes 6, and cellular proteins, either isolated or in cell membranes. The general strategy is to bind ligands to AFM tips and receptors to probe surfaces (or vice versa), respectively. In a force–distance cycle, the tip is first approached towards the surface whereupon a single receptor–ligand complex is

Nanotribology, Nanomechanics and Materials Characterizationction of material transfer, and boundary lubrication. In situ surface characterization of local deformation of materials and thin coatings can be carried out using a tensile stage inside an AFM. Mechanical properties such as hardness, Young‘s modulus of elasticity and creep/relaxation behavior can b

Here spatially resolved measurements showed that translation diffusion slows exponentially with increasi

摘要

Friction and Wear on the Atomic Scaleeriments. Even on well-defined surfaces, experiments have revealed that atomic structure is directly linked to friction force. This chapter will describe friction force microscopy experiments that reveal, more or less directly, atomic processes during sliding contact. We will begin by introducing fr

Mechanical Properties of Nanostructures of micro/nanoscale structures. Commonly used materials in MEMS/NEMS are single-crystal silicon and silicon-based materials, e.g., SiO2 and polysilicon films deposited by low-pressure chemical vapor deposition. An early study showed silicon to be a mechanically resilient material in addition to its
