AbstractAn atomic force microscope has been used to measure the frictional force on a tungsten tip sliding across the basal plane of graphite at low loads < 10-4 N. The frictional force displays the 2.5 Å periodicity of the graphite surface.

In this paper, we present experimental measurements of slip length of deionized (DI) water flow on a silicon surface and a graphite surface by using atomic force microscope. The results show that the measured hydrodynamic drag force is higher on silicon surface than that on graphite surface, and a measured slip length about 10 nm is obtained on the later surface.

For biologic studies, atomic force microscopy (AFM) has been prevailing over scanning tunneling microscopy (STM) because it has the capability of imaging non-conducting biologic specimens. However, STM generally gives better resolution than AFM, and we're talking about resolution on the atomic scale. In a recent article, Franz Giessibl (Atomic resolution of the silicon (111)- (7X7) surface by atomic force microscopy, Science 267:68-71, 1995) has demonstrated that atoms can be imaged by AFM.

Abstract It is becoming more important to observe structures and failed sites in LSIs. An atomic force microscope (AFM) can obtain atomic scale topographic images on sample surfaces. To analyze failures in LSIs, several treatments for the AFM observation, such as wet etching and mechanical polishing for a crosssectional imaging, have been proposed so far. A good correlation of AFM images using FIB anisotropic etch with those acquired by conventional technique such as SIM and TEM has been demonstrated A crystallographic information about Al thin film is obtained by AFM using this technique.

This paper deals with the description of a method for the measurement of the nanotribology properties and microscopic interfacial frictional behavior with Atomic Force Microscopy (AFM). AFM force-displacement curve is utilized to determine the nanotribology properties. The interfacial coefficient of frictional force can be derived from a serial of calculations. A well-defined contact area is measured to study the frictional force and friction stress. The roughness of contact surface influences the contact between friction and surface forces. The study of roughness parameters corresponds to evaluate the friction and the interfacial strengths. Local variation in micro/nano tribology is also measured. The measured surface topography (3D profiles) are then applied to determinate the potential energy in molecular dynamic (MD) method to study the atomic scale frictional interactions.
