Anisotropic Enhancement of Second-Harmonic Generation in Monolayer and Bilayer MoS₂ by Integrating with TiO₂ Nanowires

Abstract

/NW hybrid structure, further proving the proposed scenario. This work provides an effective approach to selectively and directionally designing the nonlinear optical response of layered TMDCs, paving the way for developing high-performance, anisotropic nonlinear photonic nanodevices.
