  • Patent number: 6071109
    Abstract: A method for producing aluminum-indium-antimony materials by metal-organic chemical vapor deposition (MOCVD). This invention provides a method of producing Al.sub.X In.sub.1-x Sb crystalline materials by MOCVD wherein an Al source material, an In source material and an Sb source material are supplied as a gas to a heated substrate in a chamber, said Al source material, In source material, and Sb source material decomposing at least partially below 525.degree. C. to produce Al.sub.x In.sub.1-x Sb crystalline materials wherein x is greater than 0.002 and less than one.

  • Patent number: 5625635
    Abstract: An infrared emitting device and method. The infrared emitting device comprises a III-V compound semiconductor substrate upon which are grown a quantum-well active region having a plurality of quantum-well layers formed of a ternary alloy comprising InAsSb sandwiched between barrier layers formed of a ternary alloy having a smaller lattice constant and a larger energy bandgap than the quantum-well layers. The quantum-well layers are preferably compressively strained to increase the threshold energy for Auger recombination; and a method is provided for determining the preferred thickness for the quantum-well layers. Embodiments of the present invention are described having at least one cladding layer to increase the optical and carrier confinement in the active region, and to provide for waveguiding of the light generated within the active region.

  • Patent number: 5326424
    Abstract: Thin films of single crystal, cubic boron nitride phosphide are provided on, and in crystallographic registry with, an underlying silicon substrate which is oriented along a single crystallographic axis. The cubic boron nitride phosphide films are deposited using laser ablation methods. The boron nitride phosphide film has a crystallographic lattice constant which can be systematically varied depending upon the desired film composition and processing parameters. Preferably, the target, and accordingly the resulting thin film composition, is characterized by a chemical formula of BN.sub.(1-x) P.sub.(x) where x is about 0.23. This particular composition results in a crystallographic lattice constant essentially equal to the single crystal silicon substrate. The film may also have the formula BN1-xPx where x<0.ltoreq.1.
