Abstract

By coating with a carbon film and graphene sheet (GS) on position-sensitive detectors based on the metal-oxide-semiconductor structure, sensitivity, linearity, and saturation power are significantly improved. We attribute this enhancement of absorptivity to lasers. The improvement effect of carbon film is more obvious than that of GS coating because of GS's high conductivity.
