Mathematical Model MM1: Electron Shuttling Model
Description: The gate electrodes form an electric potential landscape that generates an array of QDs in the QW. Suitable pulsing allows to propagate the QDs along the channel and thus enables conveyor-mode shuttling. As the device is operated at deep cryogenic temperature (50 mK), there exist no thermally activated electrons in the conduction band and space charge regions can be safely neglected. In this case, the electric potential Φ(r,t) obeys the homogeneous Poisson equation.
Properties: Is Deterministic, Is Space-Continous, Is Time-Continous, Is Linear
