✦ Synopsis

When the dimensions decrease to nano-scale, many essential phenomena appear which are not important at macro scales. In this paper, two effects of these sub-micron phenomena are demonstrated and considered for simulation of pull-in instability of beam-type nano-actuator. The first phenomenon that becomes important at nano-distances is the presence of dispersion forces such as van der Waals attraction. The second issue that must be considered in modeling nano-structures is characterization of real boundary condition. The obtained results agree well with numerical solution and other models in the literature.
