We show how Coulomb blockade of electrons in a dispersive set of clusters embedded in the dielectric of a capacitor can be used to design a voltage tunable variable capacitor (varactor). We calculate the variation of capacitance for typical size distribution of the clusters and as a function of the dielectric constants of the insulators. We also discuss the temperature and frequency dependence of the capacitor.
PACS: 73.23.Hk – Coulomb blockade; single-electron tunneling / 84.32.Tt – Capacitors / 84.37.+q – Electric variable measurements (including voltage, current, resistance, capacitance, inductance, impedance, and admittance, etc.)
