Abstract
Open quantum dots without spatial inversion symmetry can partially rectify a small AC voltage because of the asymmetric effect of an electric field on the electron interference inside the dot. Quantum dots can therefore be viewed as ratchets, that is devices in which directed particle flow is induced by non-equilibrium fluctuations, in the absence of (time-averaged) external net forces or gradients. Here we discuss thermal energy averaging and phase breaking as the parameters that limit the voltage- and temperature range where quantum dot ratchets can operate.
