Abstract
As material growth and processing have improved, state of the art infrared detector arrays remain limited by material properties and not processing or growth quality. In particular, the dark current can be dominated by diffusion of minority carriers in the quasineutral regions. In this work, we present a unique detector architecture that allows for dark current suppression below the fundamental diffusion limit. We have extensively studied this effect, and report dark current, photocurrent, and quantum efficiency. Finally, we conclude by offering a path to implementing this architecture into existing FPAs.
