Abstract :
Sputtered yttrium metal forms a thin hole-barrier contact on both p- and n-type germanium semiconductor detectors. Yttrium contacts can provide a sufficiently high hole barrier to prevent measurable contact leakage current below ∼120 K. Detectors having yttrium contacts produce good gamma-ray spectroscopy data.
