The recently found material graphene is a truly two-dimensional crystal andexhibits, in addition, an extreme mechanical strength. This in combination withthe high electron mobility favours graphene for electromechanicalinvestigations down to the quantum limit. Here, we show that a monolayer ofgraphene on SiO2 provides natural, ultra-small membranes of diameters down to 3nm, which are caused by the intrinsic rippling of the material. Some of thesenano-membranes can be switched hysteretically between two vertical positionsusing the electric field of the tip of a scanning tunnelling microscope (STM).They can also be forced to oscillatory motion by a low frequency ac-field.Using the mechanical constants determined previously, we estimate a highresonance frequency up to 0.4 THz. This might be favorable forquantum-electromechanics and is prospective for single atom mass spectrometers.
