  • Diamond transmission dynode and photomultiplier or imaging device using same
    Patent number: 6657385
    Abstract: A diamond transmission dynode and photocathode are described which include a thin layer of a crystalline semiconductive material. The semiconductive material is preferably textured with a (100) orientation. Metallic electrodes are formed on the input and output surfaces of the semiconductive material so that a bias potential can be applied to enhance electron transport through the semiconductive material. An imaging device and a photomultiplier utilizing the aforesaid transmission dynode and/or photocathode are also described.
    Type: Grant
    Filed: June 20, 2001
    Date of Patent: December 2, 2003
    Assignee: Burle Technologies, Inc.
