23_13i/2011Patterning: Templated Solid-State Dewetting to Controllably Produce Complex Patterns (Adv. Mater. 13/2011)

When single-crystal films dewet, crystalline ani-sotropy leads to the formation of patterns with regular characteristics. Lithographically pre-pat-terned films form complex structures with smaller dimensions than the original pattern, as reported by Carl V. Thompson and co-workers on p. 1567. The shape of the initial pattern affects the nature of the dewetted structure in a deterministic way, providing a new approach to complex structure formation through pattern-templated solid-state dewetting.
