Abstract
A photodetector for X-ray applications is disclosed incorporating a photodiode design with reduced leakage at each pixel location. The photodiode is of a reduced surface area and has a peripheral edge of reduced length. The length may be minimized by making the photodiode round. The diode is surrounded by a reflective layer that may act as a contact for the diode. Photons are reflected by the reflective layer back towards the reduced area diode to maintain good sensitivity. The reflective/contact layer may form a capacitor with another contact layer by disposing a dielectric layer therebetween, thereby increasing the effective capacitance of the photodiode.
