Highly Anisotropic Organometal Halide Perovskite Nanowalls Grown by Glancing‐Angle Deposition (Adv. Mater. 18/2022)

Organometal‐Halide Perovskites In article number 2107739, Ángel Barranco, Juan Ramon Sanchez‐Valencia, and co‐workers report highly aligned organometal‐halide perovskite vertical nanowalls using a new vacuum‐based approach evolved from the glancing‐angle deposition (GLAD) technique. The alignment and separation degree of the supported nanostructures are governed by the angle of deposition, which for glancing angles provides samples with strong optical anisotropic properties such as polarized‐photoluminescence or polarization‐sensitive photocurrent response.
