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.

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.

Abstract: A system is provided that predicts motor wear and failures before they occur. Telemetry data from motors in a motor application is collected and predictive algorithms are used to determine when a motor is aging and when it may fail. Identifying a potential failure in these types of applications can help mitigate risk of other equipment failures and realize cost savings. In one example, a motor aging detection system is provided that includes one or more DC motors, and a motor controller coupled to each motor. The motor controller reads three phase currents from each motor and converts the phase currents to digital values, calculates telemetry data including applied voltages, back electric-motive force, inductance, and resistance of each motor at periodic intervals, stores this telemetry data for each motor in a memory. An age detection circuit retrieves this information from the memory and determines age factors of the motor.
