Abstract: Apparatus including a substrate and a mechanical switch, the mechanical switch located over the substrate, the mechanical switch including: a first electrical contact over the substrate; a support over the substrate, the support including a region moveable relative to the first electrical contact, the moveable region having a second electrical contact, the second electrical contact located over the first electrical contact; and a self-assembled molecular layer between the substrate and the second electrical contact. Method including placing into operation an apparatus, and applying a coulomb force causing the second electrical contact to move relative to the first electrical contact such that the switch is opened or closed.
