Charge carrier doped iron pyrite nanocubes (FeS 2 NCs) exhibit strong localized surface plasmonic resonance (LSPR) spanning across ultraviolet through visible to near‐infrared (UV‐Vis‐NIR). Using the printed LSPR FeS 2 NCs/graphene van der Waals heterostructure, broadband UV‐Vis‐NIR photoresponsivity in exceeding 1.1 × 10 6 A/W has been demonstrated by Maogang Gong, Judy Z. Wu and co‐workers (article number 1701241 ) through development of a ligand‐exchange process to facilitate efficient charge transfer at the FeS 2 NCs/graphene interface.
