Abstract

Arrays of carbon nanotubes were reversibly actuated by applying a bias voltage. The actuation results in a variable capacitance between the arrays, which can be used to build a varactor. The capacitances were evaluated by simulating the scattering parameters in an equivalent electrical circuit while using the capacitance between the arrays as a fitting parameter. These simulations were compared with radio-frequency (RF) measurements on devices. A very good agreement between measurement and model was obtained. The capacitance could be varied by more than 20 per cent before the arrays were pulled into contact.
