Abstract
Imaging apparatus () includes a photosensitive medium () configured to convert incident photons into pairs of electrons and holes. An array of pixel circuits () is formed on a semiconductor substrate (). Each pixel circuit defines a respective pixel and includes an electron-collecting electrode () in contact with the photosensitive medium at a first location in the pixel and a hole-collecting electrode () in contact with the photosensitive medium at a second location in the pixel. Circuitry () is coupled to apply a positive potential to and collect the electrons from the electron-collecting electrode and to apply a negative potential to and collect the holes from the hole-collecting electrode and to output a signal indicative of an intensity of the incident photons responsively to the collected electrons and holes.
