| Popis: | This is the peer reviewed version of the following article: 2D Arrays of Hexagonal Plasmonic Necklaces for Enhanced Second Harmonic Generation, which has been published in final form at https://doi.org/10.1002/adma.201605267. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Use of Self-Archived Versions Researchers use hexagonal ferroelectric domain walls as artificial 2D sub-micrometer patterns on which strongly interacting Ag nanoparticles (NPs) can deposited forming hexagonal necklaces. Specifically, they combine ferroelectric domain engineering and polarization-mediated chemistry to obtain finely designed 2D plasmonic arrays of hexagonal supercells distributed on the polar surface of a LiNbO 3 crystal. The hexagonal plasmonic necklaces support broad radiative plasmonic resonances allowing the enhancement of second harmonic generation (SHG) at the ferroelectric domain boundaries, which act as nanometric nonlinear sources This work was supported by the Spanish Ministry of Economy and Competitiveness (MINECO) under projects MAT2013-43301-R and MAT2016-76106-R and Comunidad de Madrid under grant S2013/MIT-2740.
