Abstract
Structures for a photodetector and methods of forming a structure for a photodetector. The structure comprises a photodetector including a pad, a semiconductor layer, a first doped region in the pad, and a second doped region in the pad. The semiconductor layer adjoins the pad along an interface, and the first and doped regions are positioned adjacent to the interface.
