Electrically driven MIM nanogap antennas (Conference Presentation)
Author(s): Jean-Luc Pelouard

Paper Abstract

Promising effects such as electrical tunability of the spectral response and broadband optical emission have been demonstrated on tiny 3D resonators, opening the way to substrate-independent electrically-controlled light sources. In this talk we present the interplay between optical and electrical properties of large areas of MIM nanogap antennas. Dedicated design and low-temperature process are presented for Au/SiO2/Au structures. A drastic decrease of the effective index of the gap mode is observed for significant electron-tunneling probability (gap < 1.2nm). Electrically biased antennas show a net tunneling current together with a spectral-shift. Last but not least, light emission is characterized.
