Title: Hybrid anode for semiconductor radiation detectors

Abstract

The present invention relates to a novel hybrid anode configuration for a radiation detector that effectively reduces the edge effect of surface defects on the internal electric field in compound semiconductor detectors by focusing the internal electric field of the detector and redirecting drifting carriers away from the side surfaces of the semiconductor toward the collection electrode(s).

Nano structural anodes for radiation detectors

Patent Cordaro, Joseph V.; Serkiz, Steven M.; McWhorter, Christopher S.; ...

Anodes for proportional radiation counters and a process of making the anodes is provided. The nano-sized anodes when present within an anode array provide: significantly higher detection efficiencies due to the inherently higher electric field, are amenable to miniaturization, have low power requirements, and exhibit a small electromagnetic field signal. The nano-sized anodes with the incorporation of neutron absorbing elements (e.g., .sup.10B) allow the use of neutron detectors that do not use .sup.3He.

Semiconductor radiation detector

Patent Patt, Bradley E [Sherman Oaks, CA]; Iwanczyk, Jan S [Los Angeles, CA]; Tull, Carolyn R [Orinda, CA]; ...

A semiconductor radiation detector is provided to detect x-ray and light photons. The entrance electrode is segmented by using variable doping concentrations. Further, the entrance electrode is physically segmented by inserting n+ regions between p+ regions. The p+ regions and the n+ regions are individually biased. The detector elements can be used in an array, and the p+ regions and the n+ regions can be biased by applying potential at a single point. The back side of the semiconductor radiation detector has an n+ anode for collecting created charges and a number of p+ cathodes. Biased n+ inserts can bemore » « less

Yttrium contacts for germanium semiconductor radiation detectors

Patent Hull, Ethan; Pehl, Richard H.; Suttle, Bruce; ...

A germanium semiconductor radiation detector contact made of yttrium metal. A thin (˜1000 Å) 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 GΩ. Germanium semiconductor radiation detector diodes fabricated with yttrium contacts provide good gamma-ray spectroscopy data.
