Ultrahigh field enhancements from nanostructured metal thin films (Conference Presentation) Conference Paper uri icon

abstract

  • Enhancing the optical fields near metal nanostructures is of high importance for sensing, energy harvesting and improving the efficiency of optoelectronic devices. Surface enhanced spectroscopies such as Raman scattering (SERS), fluorescence (SEF) and infrared absorption (SEIRA) are enhanced significantly thus allowing lower detection limit and suprresolved imaging. Solar energy harvesting can be improved by designing structures that enhance the local optical field over wide spectral and angular ranges covering the whole solar spectrum. Detectors for the short wave and mid-IR ranges with higher efficiencies started to appear following an optimum designs incorporating plasmonic nanostructures. During the last few years we have been investigating several plasmonic nanostructured thin films for improved biosensors and lately for energy harvesting devices using variety of …
