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: Technologies for a transistor with a thin-film ferroelectric gate dielectric are disclosed. In the illustrative embodiment, a transistor has a thin layer of scandium aluminum nitride (ScxAl1-xN) ferroelectric gate dielectric. The channel of the transistor may be, e.g., gallium nitride or molybdenum disulfide. In one embodiment, the ferroelectric polarization changes when voltage is applied and removed from a gate electrode, facilitating switching of the transistor at a lower applied voltage. In another embodiment, the ferroelectric polarization of a gate dielectric of a transistor changes when the voltage is past a positive threshold value or a negative threshold value. Such a transistor can be used as a one-transistor memory cell.

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, such as undoped semiconductor 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 preferentially etched away, leaving the doped semiconductor layers as fins for a ribbon FET. In another embodiment, an interlayer can be deposited on top of a semiconductor layer, and a ferroelectric layer can be deposited on the interlayer. The interlayer can bridge a gap in lattice parameters between the semiconductor layer and the ferroelectric layer.
