 9 CHAPTER 3 MICRO/NANOTRIBOLOGY
The surface force apparatus (SFA), the scanning tunneling microscopes (STM), atomic force and friction force microscopes (AFM and FFM) are widely used in micro/nanotribological studies.

 10 3.1 SFA Studies
Description of an SFA
3
 11 3.2 Static Dynamic, and Shear Properties of Molecularly Thin Liquid Films
In the confinement of molecules between two structured solid surfaces
3
 12 3.3 Transition from Liquid-like to Solid-like
With a decrease in film thickness and an increase in normal stress, the film develops a yield stress, indicating a transition to a solid-like structure that must be broken down in order for sliding to occur.
3
 13 3.4 Smooth Sliding and Stick-Slip
Two surfaces with a molecularly thin liquid film in steady-state sliding still prefer to remain in one of their stable potential energy minima.
