Abstract

original image

On page 3723, Won Bo Lee, Kookheon Char, and co-workers report the fabrication of Janus nanowalls and the phenomenon of lateral buckling in the walls. To realize Janus nanowalls, metal films are deposited on one side of the polymeric nanowalls. During the metal deposition, the nanowalls themselves buckle laterally because of the compressive residual stress in the metal films and geometric constraints.
