  • Patent number: 10720539
    Abstract: An improved backsheet used in the construction of solar panels is disclosed. A method of manufacturing the backsheet and solar panel comprising the backsheet, including coextrusion processes are also disclosed. Additionally, a photovoltaic solar panel module comprising the backsheet of the invention is disclosed. The backsheet of the instant invention may comprise an exterior layer having inner and outer surfaces, a middle layer, having inner and outer surfaces, and an interior layer having inner and outer surfaces. In one embodiment of the invention, the outer surface of the middle layer may be adjoined to the inner surface of the exterior layer, and the inner surface of the middle layer may be adjoined to the outer surface of the interior layer. The exterior layer, middle layer, and interior layer may be adjoined via a co-extrusion process, thereby eliminating the need for the use of adhesives for bonding the layers of the backsheet together.

  • Patent number: 9470650
    Abstract: Sensors for sensing/measuring one or more analytes in a chemical environment. Each sensor is based on a semiconductor structure having an interfacial region containing a two-dimensional electron gas (2DEG). A catalyst reactive to the analyte(s) is in contact with the semiconductor structure. Particles stripped from the analyte(s) by the catalyst passivate the surface of the semiconductor structure at the interface between the catalyst and the structure, thereby causing the charge density in the 2DEG proximate the catalyst to change. When this basic structure is incorporated into an electronic device, such as a high-electron-mobility transistor (HEMT) or a Schottky diode, the change in charge density manifests into a change in an electrical response of the device. For example, in an HEMT, the change in charge density manifests as a change in current through the transistor, and, in a Schottky diode, the change in charge density manifests as a change in capacitance.

  • Publication number: 20160117936
    Abstract: A non-transitory processor-readable medium storing code causes a processor at a first vehicle (e.g., a first autonomous vehicle) to generate a first planned path based on a current position of the first vehicle and a mission requirement assigned to the first vehicle. A first planned path associated with a second vehicle (e.g., a second autonomous vehicle), which is based on a current position of the second vehicle and a mission requirement assigned to the second vehicle, is received at the first vehicle. After the first planned path associated with the second vehicle is received, a second planned path is generated based on the first planned path associated with the second vehicle and at least one of the mission requirement assigned to the first vehicle or the first planned path of the first vehicle. The second planned path of the first vehicle is transmitted to the second vehicle.

  • Patent number: 7829376
    Abstract: A p-type ZnO-based II-VI compound semiconductor layer has silver, potassium and/or gold dopants therein at a net p-type dopant concentration of greater than about 1×1017 cm?3. A method of forming the layer includes using an atomic layer deposition (ALD) technique. This technique includes exposing a substrate to a combination of gases: a first reaction gas containing zinc at a concentration that is repeatedly transitioned between at least two concentration levels during a processing time interval, a second reaction gas containing oxygen and a p-type dopant gas containing at least one p-type dopant species selected from a group consisting of silver, potassium and gold. A concentration of oxygen in the second reaction gas may also be repeatedly transitioned between at least two concentration levels.

  • Patent number: 7682709
    Abstract: A method of preparing an n-type epitaxial layer of aluminum nitride conductively doped with germanium comprises directing a molecular beam of aluminum atoms onto the growth surface of a substrate that provides an acceptable lattice match for aluminum nitride; directing a molecular beam of activated nitrogen to the growth surface of the substrate; and directing a molecular beam of germanium to the growth surface of the substrate; while maintaining the growth surface of the substrate at a temperature high enough to provide the surface mobility and sticking coefficient required for epitaxial growth, but lower than the temperature at which the surface would decompose or the epitaxial layer disassociate back into atomic or molecular species.

  • Patent number: 7378684
    Abstract: An underlying gallium nitride layer on a silicon carbide substrate is masked with a mask that includes an array of openings therein, and the underlying gallium nitride layer is etched through the array of openings to define posts in the underlying gallium nitride layer and trenches therebetween. The posts each include a sidewall and a top having the mask thereon. The sidewalls of the posts are laterally grown into the trenches to thereby form a gallium nitride semiconductor layer. During this lateral growth, the mask prevents nucleation and vertical growth from the tops of the posts. Accordingly, growth proceeds laterally into the trenches, suspended from the sidewalls of the posts. The sidewalls of the posts may be laterally grown into the trenches until the laterally grown sidewalls coalesce in the trenches to thereby form a gallium nitride semiconductor layer.
