Abstract: A charge carrier multiplier structure for a light sensor, in particular an ultraviolet light sensor, is described. The charge carrier multiplier structure comprises a dielectric sheet having first and second opposite faces and having an array of holes traversing the dielectric sheet between the first and second faces, at least two photocathodes supported on the first face of the dielectric sheet that are electrically isolated from each other and which define at least two sensing regions, each photocathode having a respective work function and quantum yield and having a respective area and at least one anode supported on the second face of the dielectric sheet.
