Boosting Photodetection via Plasmonic Coupling in Quasi-2D Mixed-n Ruddlesden-Popper Perovskite Nanostripes.

ABSTRACT: Quasi-2D metal halide perovskites have emerged as a promising material for photodetection due to excellent optoelectronic properties, simple synthesis, and robust stability. Albeit, developing high-performance photodetectors based on low-dimensional quasi-2D metal halide perovskite nanoparticles remains challenging due to quantum and dielectric confinement effects. Several approaches are employed to improve efficiency, with plasmonic nanostructures being among the most effective ones. Here, enhanced photodetection of quasi-2D perovskite nanostripes are demonstrated resulting from the incorporation of octadecanethiol (ODT)-functionalized Ag nanostructure arrays (ANA). Using colloidal lithography, ANA are fabricated. Reflectance spectroscopy and finite element method (FEM) simulations show t
