A method for improved growth of a semipolar (Al,In,Ga,B)N semiconductor thin film using an intentionally miscut substrate. Specifically, the method comprises intentionally miscutting a substrate, loading a substrate into a reactor, heating the substrate under a flow of nitrogen and/or hydrogen and/or ammonia, depositing an InxGa1-xN nucleation layer on the heated substrate, depositing a semipolar nitride semiconductor thin film on the InxGa1-xN nucleation layer, and cooling the substrate under a nitrogen overpressure.

摘要:
A method for growth and fabrication of semipolar (Ga, Al, In, B)N thin films, heterostructures, and devices, comprising identifying desired material properties for a particular device application, selecting a semipolar growth orientation based on the desired material properties, selecting a suitable substrate for growth of the selected semipolar growth orientation, growing a planar semipolar (Ga, Al, In, B)N template or nucleation layer on the substrate, and growing the semipolar (Ga, Al, In, B)N thin films, heterostructures or devices on the planar semipolar (Ga, Al, In, B)N template or nucleation layer. The method results in a large area of the semipolar (Ga, Al, In, B)N thin films, heterostructures, and devices being parallel to the substrate surface.

A method for the fabrication of nonpolar indium gallium nitride (InGaN) films as well as nonpolar InGaN-containing device structures using metalorganic chemical vapor deposition (MOVCD). The method is used to fabricate nonpolar InGaN/GaN violet and near-ultraviolet light emitting diodes and laser diodes.
摘要:
An improved electrical cable reel is provided which quickly and easily loads and unloads a coil of wire. The reel has an outer circular plate coupled to a vertical post for rotation about a horizontal axis. Four spaced, radially movable fingers adjacent the plate simultaneously retract inwardly as the plate is turned to a coil loading position. Once the wire coil is in place, means are provided for selectively releasing the fingers for radially outward movement under the influence of a set of springs. Consequently, the fingers rapidly engage the coil at its inner core. Subsequently, a clutch means may be operated to render the reel rotatable in either direction. The maintenance-free operating structure is safely and conveniently placed out of reach. Advantageously, the reel is mounted on a four wheeled electrical cart containing a measuring device and a wire cutter, such that various coils may be quickly changed for use on the cart.
