Superabsorbers: Efficient Mid‐Infrared Light Confinement within Sub‐5‐nm Gaps for Extreme Field Enhancement (Advanced Optical Materials 17/2017)
Source abstract
Abstract
Strong localized fields can significantly enhance the light–matter interaction at nanoscales. In article number 1700223, Qiaoqiang Gan and co-workers experimentally squeeze 81% of the incident mid-infrared radiation into a metamaterial absorber with sub-5-nm gaps fabricated using atomic layer deposition processes. The strong localized field supported in these nanogaps results in enhancement factors up to around 106–107 for surface-enhanced infrared absorption spectroscopy.
