  • Publication number: 20220189846
    Abstract: Aspects of diamond growth on semiconductors are described. Some aspects include direct growth of synthetic diamond on wide-bandgap semiconductors without the use of nucleating layers or protective layers. Some aspects include generating synthetic diamond over a gallium nitride surface of a layered structure in accordance with a set of growth parameters that are generated based at least in part on an interface property of an interface generated between the gallium nitride surface and the synthetic diamond. In some aspects, the interface is a single interface between the synthetic diamond and the gallium nitride surface. In some aspects, the synthetic diamond is in contact with the gallium nitride surface. Some aspects include synthetic diamond growth on wide-bandgap semiconductor structures to achieve thermal extraction without introducing electrically conductive regions in the semiconductor structure. Such aspects may include generating less than optimal quality synthetic diamond.

  • Patent number: 10592512
    Abstract: Techniques are provided for dynamically generating content. A request for content about a first entity is received from a client device. In response to receiving the request, an identity of a second entity of the client device is determined. Based on the identity, attributes of the second entity are identified. It is determined whether the attributes satisfy targeting criteria of a campaign that was initiated by the first entity. In response to determining that the attributes satisfy the targeting criteria, a first number of entities that (i) share one or more attributes in common with the second entity and (ii) satisfy the targeting criteria is determined. Also, a second number of entities that share the one or more attributes in common with the second entity is determined. A ratio is calculated based on the two numbers. First content that specifies the ratio is sent to the client device for display.
