Abstract:
A solid state radiation detection unit for producing pixel data from electron-hole producing radiation, including:(a) a substrate comprising a semiconductor material;(b) a plurality of metal oxide semiconductor pixel circuits incorporated into and on the substrate to form an array of pixel circuits, each of the semiconductor pixel circuits defining a pixel and including an exposed region of substrate defining a pixel contact for collecting charge indicative of pixel data;(c) a photoelectric conversion layer, deposited on the array of pixel circuits in direct contact with each pixel contact, for generating charge on exposure to selected wavelengths of electron-hole producing radiation;(d) a field electrode in contact with the photoelectric conversion layer, comprising an electrically conductive material connectable to a voltage source, for establishing an electric field between the field electrode and the pixel contacts, wherein charge generated in the photoelectric conversion layer is directly collected by the pixel contacts under the influence of the electric field.
