Strong anisotropic second-order nonlinear optical response in 0D lead-free chiral perovskite single-crystalline microwire arrays

Low-dimensional hybrid organic-inorganic chiral perovskites with intrinsic non-centrosymmetric structures have shown promising potential for second-order nonlinear optics applications due to the structural diversity and large lattice distortions. Simultaneously, “structure-level” low-dimension...
