Abstract:
An improved semiconductor radiation detector, comprising:first and second pieces of semiconductor material, wherein said pieces comprise the same or different semiconductor materials; an electrically conductive grid located at least partially within a surface of either of said first or said second pieces of said semiconductor material, wherein said electrically conductive grid includes an array of spaced electrically conductive members comprising one or more materials selected from the group consisting of one or more metals, a heavily doped semiconductor material, a superconducting material, a conductive polymer, and combinations thereof; said members formed by ion implantation or by vapor deposition, said members located in and only partially filling an array of trenches in said semiconductor material, said first and second pieces fused together adjacent said electrically conductive grid to form a radiation detector body; a cathode mounted to a first external surface of said radiation detector body opposite said electrically conductive grid; an anode mounted to a second external surface of said radiation detector body opposite said electrically conductive grid; and an electrode in contact with said array of electrically conductive members.
