Abstract
According to embodiments of the present disclosure, a dynamic photodiode may include a substrate including a major surface; a hedge formation extruding perpendicularly from the major surface; a first resettable region disposed on a top surface the hedge formation; a second resettable region disposed on the top surface of the hedge formation; a first doped region disposed on the top surface of the hedge formation between the first resettable region and the second resettable region, the first doped region including a first contact configured to receive a first voltage; and a second doped region disposed on a top surface of the hedge formation, the second doped region including a second contact configured to receive a second voltage. Exposed portions of the substrate form light absorbing regions configured to generate electron-hole pairs in the substrate.
