title: Large-Area Graphene Nanodot Array for Plasmon-Enhanced Infrared Spectroscopy.
abstract: Graphene nanodot arrays (GNDAs) are fabricated by block copolymer lithography in a high-throughput manner. The GNDA shows strong broadband plasmonic resonances in the mid-IR region with high localized field enhancement, thus allowing plasmon-enhanced infrared spectroscopy with reliable sensitivity and selectivity to be performed.
