    Abstract

    We have developed a strategy for the easy fabrication of quantum devices on AlGaAs/GaAs heterostructures featuring gates insulated from the heterostructure surface by a thin oxide layer deposited by atomic layer deposition. We will present the results of comparative studies of devices made with and without oxide-insulated gates to establish whether this leads to a significant enhancement in device stability and reduced gate hysteresis and noise.
