Abstract
A photodetector for X-ray applications includes a photodiode at each pixel location that is gated to reduce leakage of charge from the photodiode. A gate layer may be disposed around the entire peripheral edge of the detector, and maintained at a common potential with a contact layer, or at a different potential. A passivation or dielectric layer separates the gate layer from the photodiode. Leakage around the edge of the diode that can result from extended exposure to radiation is reduced by the gate layer.
