Electrochemical epitaxial (200) PbSe submicron-plates on single-layer graphene for an ultrafast infrared response

Abstract

<italic>In suit</italic> epitaxial growth of highly oriented PbSe submicron crystals on graphene <italic>via</italic> ECALE method. The hybrid PbSe/graphene structure presents a fast response and outstanding photoresponsivity under illumination of 2.7 μm light at room temperature.
