摘要: We disclose herein a photodetector comprising at least one absorption region in which photons are absorbed; and a plurality of electrodes disposed on the at least one absorption region, the electrodes being spaced apart from one another. In use, the geometry of at least one electrode is chosen to enhance the formation of an electric field of the requisite magnitude for avalanche multiplication to occur near the at least one electrode.
