Abstract:
The first object of the invention is directed to a UV detector comprising a p-n junction with a substrate coated with a layer of p-type oxide material, said p-type oxide material being coated with a layer of n-type oxide material which is ZnO. Said UV detector is remarkable in that said p-type oxide material consists of CuCrO2, wherein the ratio Cr/Cu ratio within said layer of p-type oxide material is >1. The second object of the invention is directed to a method for producing said UV-visible detector. It comprises the step of assembling at least one p-n junction with optical means adapted for sensing UV light. The use of said UV-visible detector as flame detector is also disclosed.

Abstract:
Novel Group II metal MOCVD precursor compositions are described having utility for MOCVD of the corresponding Group II metal-containing films. The complexes are Group II metal beta -diketonate Lewis base adducts having ligands such as: (i) amines bearing terminal NH2 groups; (ii) imine ligands formed as amine (i)/carbonyl reaction products; (iii) combination of two or more of the foregoing ligands (i)-(ii), and (iv) combination of one or more of the foregoing ligands (i)-(ii) with one or more other ligands or solvents.

Abstract:
The present invention is directed to a system and method which imparts quality control testing to a reel-to-reel superconductor manufacturing line. The quality control testing will ensure the characteristics of the final superconductor tape, as well as the tape under process. The quality control testing may be used to control and/or change production parameters (e.g. temperature, pressure, gas concentrations, precursor amounts, etc).
Abstract:
The invention continuously deposits materials used to grow a thin film onto a moving tape. The invention preferably uses a pay-out reel (401) and take-up reel (406) to respectively dispense and spool the tape substrate (408) at a constant rate. The invention preferably uses a series of stages to form the thin film on the tape, and includes at least one reactor or reaction chamber (601c) to deposit one or more materials onto the tape substrate that is used to form the superconductor layer, and one or more chambers (601a, 601b) to deposit buffer layers between the film and the metal tape substrate or between layers of film, as well as for the deposition of coating layers. The invention also preferably uses transition chambers (701) between the stages to isolate each stage from the other stages.
