Abstract

Metal nanostructures with nanogap features have proven highly effective as building blocks for plasmonic systems as they can provide a wide tuning range of operating frequencies and large near-field enhancements. It has recently become apparent that quantum mechanical effects such as nonlocality and electron tunnelling become important as the gap separations approach the subnanometre length-scale. Such quantum effects challenge the classical picture of nanogap plasmons and have stimulated a number of theoretical and experimental studies. In this review, we outline the major findings of these efforts, and discuss remaining challenges and future directions.
