Abstract: The present disclosure describes porous GaN layers and/or compliant substrates used to enable relaxation of previously strained top layers and the deposition of relaxed or partially relaxed on top. Relaxed In GaN layers are fabricated without generation of crystal defects, which can serve as base layers for high performance long wavelength light emitting devices (LEDs, lasers) solar cells, or strain engineered transistors. Similarly, relaxed AlGaN layers can serve as base layers for high performance short wavelength UV light emitting devices (LEDs, lasers) solar cells, or wide bandgap transistors.

Abstract: Systems and methods for providing metric data for patterns in a modeling environment are disclosed. In some aspects, contexts for generating metric data for a pattern are constructed. The pattern represents one or more computations executable in the modeling environment and associated with operation or behavior of a real-world system. The contexts include information about the pattern. The metric data is associated with one or more objectives with which the use of the pattern is associated. Code for the pattern for each context is generated. Metric data is generated for the pattern and under each context. The metric data of the pattern under each context is associated with the objectives. The metric data and the association are stored for use in providing information about or based on the metric data when the pattern is to be or is used in a model representing the real-world system.

Abstract: An optoelectronic or electronic device structure, including an active region on or above a polar substrate, wherein the active region comprises a polar p region. The device structure further includes a hole supply region on or above the active region. Holes in the hole supply region are driven by a field into the active region, the field arising at least in part due to a piezoelectric and/or spontaneous polarization field generated by a composition and grading of the active region.

Abstract: Techniques are disclosed for time constrained electronic request evaluation. A server system receives, from a computing device, a request submitted via an account, including a first set of characteristics associated with the request. The system executes a first machine-learning model to determine a first risk score for the request by inputting the first set of characteristics into the first model. The system generates an initial authentication decision for the request based on the first score and sends the decision to the device. The system executes a second, different machine-learning model to determine a second risk score for the request, by inputting the first set of characteristics and a second, different set of characteristics associated with the account into the second model. Based on the second score, the system determines a final authentication decision. The disclosed techniques may advantageously improve computer security and operations via identification of malicious electronic requests.

Abstract: Strain is used to enhance the properties of p- and n-materials so as to improve the performance of III-N electronic and optoelectronic devices. In one example, transistor devices include a channel aligned along uniaxially strained or relaxed directions of the III-nitride material in the channel. Strain is introduced using buffer layers or source and drain regions of different composition.

Abstract: Trenched vertical power field-effect transistors with improved on-resistance and/or breakdown voltage are fabricated. In one or more embodiments, the modulation of the current flow of the transistor occurs in the lateral channel, whereas the voltage is predominantly held in the vertical direction in the off-state. When the device is in the on-state, the current is channeled through an aperture in a current-blocking region after it flows under a gate region into the drift region. In another embodiment, a novel vertical power low-loss semiconductor multi-junction device in III-nitride and non-III-nitride material system is provided. One or more multi-junction device embodiments aim at providing enhancement mode (normally-off) operation alongside ultra-low on resistance and high breakdown voltage.

Abstract: A system and method for deduplicating messages is provided. Duplicate copies of messages are excluded from a set of deduplicated messages. The set of deduplicated messages can then be sampled to obtain a sample set usable for ensuring compliance according to a set of rules. One method for deduplicating messages involves receiving a message, determining whether the message is a duplicate copy, and adding the message to the set of deduplicated messages, if it is determined that the message is not a duplicate copy.
