Abstract
In this talk, we will present how metamaterials can be used for nanobiosensors and nanophotode-tector applications. We will present a label-free, optical nano-biosensor based on the Localized Surface Plasmon Resonance (LSPR) effect that is observed at the metal-dielectric interface of sil-ver nano-cylinder arrays located periodically on a sapphire substrate by E-Beam Lithography (EBL), which provides high resolution and flexibility in patterning. We will also report on UV plasmonic antenna integrated metal semiconductor metal (MSM) photodetectors based on GaN. We also report the design, fabrication, and measurement of a device comprising a split-ring resonator array on epitaxial graphene.
