Manipulation of Fractal Nano‐Kirigami by Capillary and Electrostatic Forces (Advanced Optical Materials 1/2023)

In article number 2202150, Xiaorong Hong, Chang-Yin Ji, Jiafang Li, and co-workers demonstrate fractal nano-kirigami structures with rotational symmetries. Structural deformations with strong fractal dependence are manipulated by employing capillary and electrostatic forces, respectively. The fractal nano-kirigami structures are envisioned to provide the capability of conveniently generating fractal-dependent optical vortices. This special fractal design strategy opens a new avenue for designing and reconfiguring functional 3D micro/nano structures with improved optical tunability and customization.
