Abstract

<p>Graphene is a carbon-based atomically thin two-dimensional material that exhibits various excellent optical and electronic properties that cannot be demonstrated by conventional bulk materials. In particular, the broadband photodetection ability, high carrier mobility, and low environmental impact of graphene are advantageous for infrared (IR) sensor applications. In this article, the expectations and challenges for graphene-based optical sensor applications are clarified and the photodetection mechanism for graphene-based optical sensors is explained. Photogating, which was introduced as a promising method for enhancing sensor responsivity, is then discussed. Finally, both individual graphene photogated diodes (GPDs), which exhibit a high responsivity and low dark current, and graphene-based IR image sensors fabricated from a large array of such GPDs, are reviewed. </p>
