Electro-mechanical to optical conversion by plasmonic-ferroelectric nanostructures

Abstract Barium titanate (BaTiO 3 ) is a lead-free ferroelectric crystal used in electro-mechanical transducers and electro-optic films. Nanomechanical devices based on thin films of BaTiO are still unavailable, as the internal stress results brittle fracture. Here, we use force to fabricate deformable assemblies (nanobeams) nanocrystals, top plasmonic metasurfaces. The mechanical deformation nanobeams driven by piezoelectric response nanocrystals. plasmonic-ferroelectric nanostructures due enhancement enable subwavelength interaction lengths support reflection modulation up 2.936 ± 0.008%. Their frequency tested across 50 kHz 2 MHz dependent oscillations nanobeams. nonlinearities, which offer additional control over optical conversion.
