  • Yttrium contacts for germanium semiconductor radiation detectors
    Patent number: 8729656
    Abstract: A germanium semiconductor radiation detector contact made of yttrium metal. A thin (˜1000 ?) deposited layer of yttrium metal forms a thin hole-barrier and/or electron-barrier contact on both p- and n-type germanium semiconductor radiation detectors. Yttrium contacts provide a sufficiently high hole barrier to prevent measurable contact leakage current below ˜120 K. The yttrium contacts can be conveniently segmented into multiple electrically independent electrodes having inter-electrode resistances greater than 10 G?. Germanium semiconductor radiation detector diodes fabricated with yttrium contacts provide good gamma-ray spectroscopy data.
    Type: Grant
