摘要： A photodetector device is provided that includes a ROIC having a top surface with a plurality of electrically conductive first electrodes within a pattern of surface areas on the top surface each surface area having a border, and an electrically conductive electrode grid having a portion on the border of each of the surface areas; and a photodetector film overlying the surface area. The electrode grid can be configured to surround each surface area to define the borders of the surface areas as pixels. The photodetector film can be a colloidal quantum dot film. The ROIC has circuit elements signal-connected to the plurality of first electrodes. Methods for forming the photodetector device include photolithography and deposition methods.
