Stiction is a portmanteau of "static" and "friction." It refers to the force that must be overcome to initiate motion between two surfaces in contact at rest. In the realm of nanotechnology, stiction is particularly significant due to the dominant influence of surface forces at the nanoscale. Unlike macroscopic systems where gravity and inertia are predominant, nano-systems are largely governed by surface interactions such as van der Waals forces, electrostatic forces, and capillary forces.
