Charge control in acoustic charge transport devices

Acoustic charge transport (ACT) devices utilize the acoustoelectric effect in a piezoelectric semiconductor, particularly GaAs, to create buried channel charge transfer devices capable of signal processing functions, especially transversal filtering. Charge control in ACT devices concerns the control and accounting of charge with the goal of preserving signal integrity. Two key aspects of charge control are the influence of perturbing channel potentials on the ACT properties, which are principally charge capacity and transfer efficiency, and the charge storage process, which is the inhibition of ACT via barrier potentials applied to surface electrodes. Several charge control topics are investigated in this work using experimental devices and numerical modeling.
