Patent number: 10502842Abstract: Technologies are described for semiconductor radiation detectors. The semiconductor radiation detectors may comprise a semiconductor material. The semiconductor material may include a first surface and a second surface. The first surface may be opposite from the second surface. The semiconductor material may include at least one metal component. The semiconductor material may be effective to absorb radiation and induce a current pulse in response thereto. The semiconductor radiation detector may comprise an electrode contact. The electrode contact may include a metal doped oxide deposited on the first surface of the semiconductor material. The metal doped oxide may include the metal component element of the semiconductor material.Type: GrantFiled: February 12, 2016Date of Patent: December 10, 2019Assignees: BROOKHAVEN SCIENCE ASSOCIATES, LLC, NORFOLK STATE UNIVERSITYInventors: Utpal N. Roy, Ralph B. James, Giuseppe Camarda, Yonggang Cui, Anwar Hossain, Ge Yang, Aswini Pradhan, Rajeh Mundle

Patent number: 9437692Abstract: Technologies are described effective to implement systems and methods of producing a material. The methods comprise receiving a tertiary semiconductor sample with a dilute species. The sample has two ends. The first end of the sample includes a first concentration of the dilute species lower than a second concentration of the dilute species in the second end of the sample. The method further comprises heating the sample in a chamber. The chamber has a first zone and a second zone. The first zone having a first temperature higher than a second temperature in the second zone. The sample is orientated such that the first end is in the first zone and the second end is in the second zone.Type: GrantFiled: October 25, 2013Date of Patent: September 6, 2016Assignee: Brookhaven Science Associates, LLCInventors: Ralph B.

Patent number: 9335423Abstract: A radiation detector device is provided that is capable of distinguishing between full charge collection (FCC) events and incomplete charge collection (ICC) events based upon a correlation value comparison algorithm that compares correlation values calculated for individually sensed radiation detection events with a calibrated FCC event correlation function. The calibrated FCC event correlation function serves as a reference curve utilized by a correlation value comparison algorithm to determine whether a sensed radiation detection event fits the profile of the FCC event correlation function within the noise tolerances of the radiation detector device. If the radiation detection event is determined to be an ICC event, then the spectrum for the ICC event is rejected and excluded from inclusion in the radiation detector device spectral analyses. The radiation detector device also can calculate a performance factor to determine the efficacy of distinguishing between FCC and ICC events.Type: GrantFiled: June 29, 2012Date of Patent: May 10, 2016Assignee: Brookhaven Science Associates, LLCInventors: Aleksey E.

Patent number: 8063378Abstract: The preferred embodiments are directed to a high-energy detector that is electrically shielded using an anode, a cathode, and a conducting shield to substantially reduce or eliminate electrically unshielded area. The anode and the cathode are disposed at opposite ends of the detector and the conducting shield substantially surrounds at least a portion of the longitudinal surface of the detector. The conducting shield extends longitudinally to the anode end of the detector and substantially surrounds at least a portion of the detector. Signals read from one or more of the anode, cathode, and conducting shield can be used to determine the number of electrons that are liberated as a result of high-energy particles impinge on the detector. A correction technique can be implemented to correct for liberated electron that become trapped to improve the energy resolution of the high-energy detectors disclosed herein.Type: GrantFiled: March 27, 2008Date of Patent: November 22, 2011Assignee: Brookhaven Science Associates, LLCInventors: Aleksey E.
