Abstract
The present disclosure provides techniques for improving the rate and efficiency of charge transfer within an integrated circuit configured to receive incident photons. Some aspects of the present disclosure relate to integrated circuits that are configured to induce one or more intrinsic electric fields that increase the rate and efficiency of charge transfer within the integrated circuits. Some aspects of the present disclosure relate to integrated circuits configured to induce a charge carrier depletion in the photodetection region(s) of the integrated circuits. In some embodiments, the charge carrier depletion in the photodetection region(s) may be intrinsic, in that the depletion is induced even in the absence of external electric fields applied to the integrated circuit. Some aspects of the present disclosure relate to processes for operating and/or manufacturing integrated devices as described herein.
