Electronic elements based on quasitwo-dimensional electron/hole gas at charged domain walls in ferroelectrics

The present invention relates to a device including a ferroic material having a ferroelectric order parameter and including at least two domains, as well as a first and second electrode in electrical contact with the ferroic material. The device is configured to form a head-to-head polarization orientation or a tail-to-tail polarization orientation at an interface between the two domains to form a charged domain wall at said interface and between the first and second electrodes. The present invention relates to a corresponding method for operating such a device.
