Nanotribological Phenomena, Principles and Mechanisms for MEMS,rgy, surface topography, environment, etc. play major roles in nanotribology. The experimental study of nanotribology is made possible by using surface force apparatus (SFA), atomic force microscope (AFM), friction force microscope (FFM), and ball-on-disk nanotribometer. Tribology research exceeding

Mechanical Properties and Deformation Behavior of Ni Nanodot-Patterned Surfaces,niques are described, which include methods of fabricating and characterizing Ni NDPSs as well as studying the mechanical properties and deformation behavior of NDPSs using nanoindentation. Third, methods of determining mechanical properties of Ni nanodots from nanoindentation experiments are presen
