Abstract

An apparatus for suppressing electron/hole recombination includes a photonic device that generates electron/hole pairs responsive to a light beam interacting with the photonic device. An orbital angular momentum (OAM) generation device is located to impart an orbital angular momentum to a light beam before the light beam interacts with the photonic device. The electron/hole pair recombination generated from an OAM imparted light beam is less than electron/hole pair recombination of a non-OAM imparted light beam.
