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
