The faceting of unstable crystal surfaces provides self-assembling templates for soft lithography, enabling the facile generation of a variety of periodic nanopatterned monolayers, nanowires, nanogrooves, nanogrids, and nanowaffles of Au and Si (the figure shows the replication of faceted sapphire to an elastomeric stamp, and then to a patterned self-assembled monolayer).
