Modelling of adhesive forces in nanotweezer

摘要：

In nano manipulation, carbon nanotubes (CNT) mounted on the AFM tip was used for pick and place of the nano size objects. In releasing step, the van der Waals adhesive force among the object and the contact surfaces of the gripper is not still well understood. In this paper, the adhesive electrostatic force, van der Waals (VDW) force between two cantilever tips and VDW force among cantilevers and the object are considered as dominant forces to pick and place the nano object. The equations governed on nanotweezer are solved using FEM code. The effect of object size, gap size and tips length on pull-in voltage are evaluated. The presented model could be used to design the tweezers for pick and place of sizedefined nano object mounted on microgripper.
