Abstract

A path-length bias of nucleated electrochemical growth in a 3D periodic nano-maze is found to cause facet formation of an intrinsically isotropic material in a porous self-assembled gyroid network. This is the first report of faceted electrochemical growth that is not based on the crystallographic order of the constituent building blocks, but rather reflects the symmetry of the template in which the material is synthesized.

Keywords: copolymer self-assembly; double-gyroid; faceted growth; platinum electrodeposition; three-dimensional nanostructure.
