Decoding Directional Control in Metal‐Assisted Chemical Etching via Catalyst Architecture

open access: yesAdvanced Materials, EarlyView.
Metal‐assisted chemical etching (MaCE) enables silicon nanostructure fabrication but suffers from isotropic undercutting. This study highlights the critical role of catalyst morphology in etching directionality. High‐aspect‐ratio catalysts induce lateral etching, while thermal treatment at 450 °C stabilizes catalyst geometry, promoting vertical etching.
