Abstract
We have demonstrated a performance enhanced multicolor quantum grid infrared photodetector (QGIP) through graphene overlaying. The responsivity and the detectivity are improved due to the photoelectrons extra-generated at the Graphene-GaAs interface contribute to the photocurrent. CLEO 2020 ? OSA 2020 ? 2020 The Author(s).
