Abstract: A single crystal thin film of the compound ZnSiXGe1-XN2 (where x can range from 0 to 1). This thin film single crystal can be disposed on a single crystal substrate made of, for example, sapphire, silicon carbide, lithium gallate or silicon with or without an additional GaN buffer layer grown on them. Alternately, a GaN single crystal thin film grown on any substrate can be used. In the case of sapphire, it can be R-plane so that the thin film has its c-axis lying within the thin film or A- or C-plane so that the thin film has its c-axis perpendicular to the substrate. The substrate could also be any substrate with a GaN single crystal thin film deposited on it. ZnSiXGe1-XN2 single crystal thin films can be made by the MOCVD method using suitable precursors, molar injection ratios, and substrate temperatures. It is possible to make various optical, electro-optical or electronic devices with the material, for example, a second harmonic generator emitting blue light.

Abstract: The present invention provides for a chemical vapor deposition reactor cher which is fitted with a rotatable and vertically movable susceptor/wafer carrier. The susceptor/wafer carrier, which is a large diameter disk, provides the reactor with the capability of varying the plasma-substrate distance. As those skilled in the art will appreciate, such a susceptor allows high deposition rates to be achieved for a given power level because the flux of the reactant can be increased due to the high speed rotation which will decrease boundary layer thickness during growth. The ability to adjust the source-substrate distance gives more flexibility than fixed dimensional systems. Further, it allows damage in the thin films to be minimized by simple adjustments to the susceptor/wafer carrier. Because the damage to the thin films is minimized, it makes pulsed operation practical and therefore, the films may be grown in an atomic layer epitaxy mode to produce films of high quality and uniformity.

Abstract: Apparatus for supporting a group of optical fibers in proper alignment with associated laser devices and rear-facet photodetectors. The photodetectors and grooves for supporting the optical fibers are fabricated in a carrier member of device quality silicon. An array of a row of laser devices is moved laterally along a slot in the carrier member transverse to the grooves so as to align each laser device with a groove and with a photodetector. One or more carrier members may be mounted on a supporting structure adapted to receive them.

Abstract: Method of fabricating a monolithic integrated circuit structure incorporating a complementary pair of GaAs/AlGaAs modulation-doped field effect transistors (MODFET's) including providing a substrate of semi-insulating GaAs, depositing an epitaxial layer of undoped AlGaAs on its surface, and ion-implanting a heavily doped N-type donor region and a heavily doped P-type acceptor region in the undoped AlGaAs. A thin spacer layer of undoped AlGaAs is epitaxially deposited on the previously deposited AlGaAs layer, and an epitaxial layer of undoped GaAs is deposited on the spacer layer. First and second gate members which form Schottky barriers with the GaAs are placed on the GaAs layer overlying portions of the N-type donor region and P-type acceptor region, respectively. N-type source and drain zones are formed in the GaAs layer on opposite sides of the first gate member, and P-type source and drain zones are formed in the GaAs layer on opposite sides of the second gate member.

Abstract: An enhanced mobility buried channel transistor structure in which the quasi-two-dimensional electron gas (2DEG) which forms the conducting channel in the structure is removed from the proximity of the heterointerface, and is placed in a region remote therefrom. A "tapered" layer of Al.sub.x Ga.sub.1-x As is provided, where x varies from maximum to minimum as the interface with an undoped layer of GaAs is approached.
