Multimodal plasmonic resonances: Silicon nanowires that contain multiple, dimensionally controlled, axially registered doped regions were synthesized and investigated by angle-dependent mid-infrared spectroscopy (see picture; P=partial pressure). The wires support mid-infrared multimodal localized surface plasmon resonances.
