Inducing Strong Light-Matter Coupling and Optical Anisotropy in Monolayer MoS₂ with High Refractive Index Nanowire.

ABSTRACT: Mixed-dimensional heterostructures combine the merits of materials of different dimensions; therefore, they represent an advantageous scenario for numerous technological advances. Such an approach can be exploited to tune the physical properties of two-dimensional (2D) layered materials to create unprecedented possibilities for anisotropic and high-performance photonic and optoelectronic devices. Here, we report a new strategy to engineer the light-matter interaction and symmetry of monolayer MoS₂ by integrating it with one-dimensional (1D) AlGaAs nanowire (NW). Our results show that the photoluminescence (PL) intensity of MoS₂ increases strongly in the mixed-dimensional structure because of electromagnetic field confinement in the 1D high refractive index semiconduct
