摘要： A laterally contacted blue LED device involves a PAN structure disposed over an insulating substrate. The substrate may be a sapphire substrate that has a template layer of GaN grown on it. The PAN structure includes an re¬ type GaN layer, a light-emitting active layer involving indium, and a p-type GaN layer. The n-type GaN layer has a thickness of at least 500nm. A Low Resistance Layer (LRL) is disposed between the substrate and the PAN structure such that the LRL is in contact with the bottom of the n- layer. In one example, the LRL is an AlGaN/GaN superlattice structure whose sheet resistance is lower than the sheet resistance of the n-type GnA layer. The LRL reduces current crowding by conducting current laterally under the n-type GaN layer. The LRL reduces defect density by preventing dislocation threads in the underlying GaN template from extending up into the PAN structure.

摘要： A vertical GaN-based blue LED has an n-type GaN layer that was grown directly on Low Resistance Layer (LRL) that in turn was grown over a silicon substrate. In one example, the LRL is a low sheet resistance GaN/AlGaN superlattice having periods that are less than 300nm thick. Growing the n-type GaN layer on the superlattice reduces lattice defect density in the n-type layer. After the epitaxial layers of the LED are formed, a conductive carrier is wafer bonded to the structure. The silicon substrate is then removed. Electrodes are added and the structure is singulated to form finished LED devices. In some examples, some or all of the LRL remains in the completed LED device such that the LRL also serves a current spreading function. In other examples, the LRL is entirely removed so that no portion of the LRL is present in the completed LED device.

摘要： A vertical GaN-based blue LED has an n-type GaN layer that was grown over a ZnS layer that in turn was grown directly on a silicon substrate. In one example, the ZnS layer is a transitional buffer layer that is 50nm thick, and the n-type GaN layer is at least 2000nm thick. Growing the n-type GaN layer on the ZnS buffer layer reduces lattice defect density in the n-type layer. The ZnS buffer layer provides a good lattice constant match with the silicon substrate and provides a compound polar template for subsequent GaN growth. After the epitaxial layers of the LED are formed, a conductive carrier is wafer bonded to the structure. The silicon substrate and the ZnS buffer layer are then removed. Electrodes are added and the structure is singulated to form finished LED devices.

摘要： A buffer layer of zinc telluride (ZnTe) or titanium dioxide (TiO 2 ) is formed directly on a silicon substrate. Optionally, a layer of A1N is then formed as a second layer of the buffer layer. A template layer of GaN is then formed over the buffer layer. An epitaxial LED structure for a GaN-based blue LED is formed over the template layer, thereby forming a first multilayer structure. A conductive carrier is then bonded to the first multilayer structure. The silicon substrate and the buffer layer are then removed, thereby forming a second multilayer structure. Electrodes are formed on the second multilayer structure, and the structure is singulated to form blue LED devices.

摘要： A vertical GaN-based blue LED has an n-type layer comprising multiple conductive intervening layers. The n- type layer contains a plurality of periods. Each period of the n-type layer includes a gallium-nitride (GaN) sublayer and a thin conductive aluminum-gallium-nitride (AlGaN:Si) intervening sublayer. In one example, each GaN sublayer has a thickness substantially more than lOOnm and less than lOOOnm, and each AlGaN:Si intervening sublayer has a thickness less than 25nm. The entire n-type layer is at least 2000nm thick. The AlGaN:Si intervening layer provides compressive strain to the GaN sublayer thereby preventing cracking. After the epitaxial layers of the LED are formed, a conductive carrier is wafer bonded to the structure. The silicon substrate is then removed. Electrodes are added and the structure is singulated to form a finished LED device. Because the AlGaN:Si sublayers are conductive, the entire n-type layer can remain as part of the finished LED device.
摘要翻译：垂直的GaN基蓝色LED具有包括多个导电中间层的n型层。 n型层包含多个周期。 n型层的每个周期包括氮化镓（GaN）子层和薄导电铝 - 氮化镓（AlGaN：Si）介入子层。在一个示例中，每个GaN子层的厚度基本上大于100nm且小于1000nm，并且每个AlGaN：Si中间层具有小于25nm的厚度。整个n型层的厚度至少为2000nm。 AlGaN：Si中间层为GaN子层提供压缩应变，从而防止开裂。在形成LED的外延层之后，将导电载体晶片结合到该结构上。然后去除硅衬底。添加电极，并且将结构单个化以形成成品的LED器件。因为AlGaN：Si子层是导电的，所以整个n型层可以保留为最终的LED器件的一部分。

摘要： The invention relates to a reactor comprising two reaction zones and processes for the production of alkenes from alkanes. A first reaction zone includes a combustion catalyst, and a second reaction zone comprises a heating zone in thermal contact with the first reaction zone. One process comprises generating heat and an effluent by the combustion of a fuel with oxygen in the first reaction zone; passing an alkane feed through the heating zone of the second reaction zone such that the alkane feed absorbs a sufficient amount of the heat generated in the first reaction zone to initiate the conversion of alkanes to alkenes in the second reaction zone. In other embodiments, the effluent comprises oxygen, and the second reaction zone excludes a catalyst; alternatively, the effluent is substantially free of oxygen, and the second reaction zone comprises a supplemental oxygen feed and may or may not include a catalyst.

摘要： It is essential to propose a new scan testing scheme that efficiently compresses stimulus data and compacts test responses, provides low-power feature, and reduces test application cost significantly. A new test response compaction scheme called selective test response collection is proposed to reduce test response data, which is combined with a structure-analysis-based test response compactor by using a new coordination measure. The scan architecture is also established considering the coordination relationship between scan flip-flops. A new low-power test application scheme is proposed, which is able to compress test data very well and the test application time remains at the level of multiple scan chain designs. A combination of a scan architecture and an existent test compression scheme can greatly compress test data.
