  • Germanium semiconducting radiation detector with phosphorus implanted n.sup.+ contact
    Patent number: 4415916
    Abstract: Germanium detectors usable for charged particle spectroscopy and capable of enduring overvoltage without impairment are produced by first implanting phosphorus ions of high energy in a small dose and then implanting more phosphorus ions of lower energy in a large dose. The low energy ions reduce surface resistance without impairing the improved properties of withstanding overvoltage that are provided by the high energy implantation. The p.sup.+ contact is provided by boron ion implantation in a conventional manner. "Dead zones" on both sides have been found to have a very small thickness of 0.3 .mu.m.

  • P-I-N Diode detector of ionizing radiation with electric field straightening
    Patent number: 4166218
    Abstract: The distortion of the electric field in a p-i-n diode detector produced by lectrically active layer build-up on the exposed surface of the i zone is removed by irradiating the exposed i zone surface with a light source having the intensity of a few milliwatts.
