    Abstract: A position-sensitive photodetector device includes a grid of series-connected photodetectors that are electrically coupled to either a vertical photodetector array (VA photodetectors) or to a horizontal photodetector array (HA photodetectors). The VA and HA photodetectors are arranged in an alternating sequence along rows and/or columns throughout the grid. A horizontal-position readout line is electrically coupled to a termination of each vertical photodetector array, and a vertical-position readout line is electrically coupled to a termination of each horizontal photodetector array.

    Abstract: A photodetector includes an array of pixels, each pixel comprising a defined doped region defined in a doped semiconductor layer. The defined doped region is defined by selected regions of ion implants to provide resistive isolation between each defined doped region. A capacitor is formed by the defined doped region and a metal layer disposed above the doped semiconductor layer. A contact metal line is disposed above the doped semiconductor layer. The capacitor metal and contact metal lines are electrically coupled together and are in electrical communication with the output of the photodetector array.

    Abstract: A gamma-ray detector includes a plurality of modular one-dimensional arrays of monolithic detector sub-modules. Each monolithic detector sub-module includes a scintillator layer, a light-spreading layer, and a photodetector layer. The photodetector layer comprises a two-dimensional array of photodetectors that are arranged in columns and rows. A common printed circuit board is electrically coupled to the photodetectors of the monolithic detector sub-modules of a corresponding modular one-dimensional array. The photodetectors can be electrically coupled in a split-row configuration or in a checkerboard configuration. The photodetectors can also have a differential readout.
