Non-plasmonic nanoantennas for surface enhanced spectroscopies with ultra-low heat conversion
Nanoplasmonics has recently revolutionized our ability to control light on the nanoscale. Using metallic nanostructures with tailored shapes, it is possible to efficiently focus light into nanoscale field 'hot spots'. High field enhancement factors have been achieved in such optical nanoan...
