Abstract: A two-terminal ferroelectric perovskite diode comprises a region of ferroelectric perovskite material positioned adjacent to a region of n-type doped perovskite semiconductor material. Asserting a positive voltage across the diode can cause the polarization of the ferroelectric perovskite material to be set in a first direction that causes the diode to be placed in a low resistance state due to the formation of an accumulation region in the perovskite semiconductor material at the ferroelectric perovskite-perovskite semiconductor boundary. Asserting a negative voltage across the diode can cause the polarization of the ferroelectric perovskite material to be set in a second direction that causes the diode to be placed in a high resistance state due to the formation of a depletion region in the perovskite semiconductor material at the ferroelectric perovskite-perovskite semiconductor material. These non-volatile low and high resistance states enable the diode to be used as a non-volatile memory element.

Abstract: Technologies for a field effect transistor (FET) with a ferroelectric gate dielectric are disclosed. In an illustrative embodiment, a perovskite stack is grown on a buffer layer as part of manufacturing a transistor. The perovskite stack includes one or more doped semiconductor layers alternating with other lattice-matched layers. Growing the doped semiconductor layers on lattice-matched layers can improve the quality of the doped semiconductor layers. The lattice-matched layers can be etched away, leaving the doped semiconductor layers as fins for a ribbon FET. A ferroelectric layer can be conformally grown on the fins, creating a high-quality ferroelectric layer above and below the fins. A gate can then be grown on the ferroelectric layer.

Abstract: A transistor device may be formed with a doped perovskite material as a channel region. The doped perovskite material may be formed via an epitaxial growth process from a seed layer, and the channel regions of the transistor device may be formed from lateral overgrowth from the epitaxial growth process.

Abstract: Technologies for a field effect transistor (FET) with a ferroelectric gate dielectric are disclosed. In an illustrative embodiment, a transistor includes a gate of strontium ruthenate and a ferroelectric gate dielectric layer of barium titanate. In order to prevent migration of ruthenium from the strontium ruthenate to the barium titanate, a barrier layer is placed between the gate and the ferroelectric gate dielectric layer. The barrier layer may be a metal oxide, such as strontium oxide, barium oxide, zirconium oxide, etc.

Abstract: Perovskite oxide field effect transistors comprise perovskite oxide materials for the channel, source, drain, and gate oxide regions. The source and drain regions are doped with a higher concentration of n-type or p-type dopants (depending on whether the transistor is an n-type or p-type transistor) than the dopant concentration in the channel region to minimize Schottky barrier height between the source and drain regions and the source and drain metal contact and contact resistance.
