"Antenna-coupled light emission from two-dimensional materials." <i>Micro- and Nanotechnology Sensors, Systems, and Applications IX,</i> (2017) SPIE: https://doi.org/10.1117/12.2262152.https://hdl.handle.net/1911/98884We have studied the ultrafast conversion of electrons localized in vertical Au-hBN-Au tunnel junctions to free-space photons, mediated by resonant slot antennas. We achieve polarized, directional and resonantly enhanced light emission from inelastic electron tunneling and establish a novel platform for studying the interaction of electrons with strong electromagnetic fields. Further, we show that plasmonic antennas made from a gold nanoparticle dimer coupled with a semiconducting 2D material (MoS2) offer control over emission directionality.engThis is an author's peer-reviewed final manuscript, as accepted by the publisher.
