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: 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: Techniques are disclosed relating to database query optimizers. In some embodiments, a query parser of a database system receives a query requesting data from a multi-tenant database. The query includes a first constraint that restricts a query optimizer's selection of a set of execution plans available to implement the query. The database system determines whether an override has been specified for a particular tenant associated with the received query, the override indicating that the first constraint is to be replaced with a second constraint for the particular tenant. In response to determining that the override has been specified for the particular tenant, the database system replaces the first constraint in the query with the second constraint and provides the query with the second constraint to the query optimizer for selection of an execution plan in accordance with the second constraint.
