23_28/2011Electromechanical Responses: Nanoscale Structure and Mechanism for Enhanced Electromechanical Response of Highly Strained BiFeO3 Thin Films (Adv. Mater. 28/2011)

A rugged landscape for high-performance electromechanical responses is reported on p. 3170 by Lane W. Martin and co-workers. The cover image shows a high-resolution atomic force microscopy image of the complex surface structure of a highly strained BiFeO3 thin film. The presence of several structural variants in these films gives rise to exotic electric-field-induced responses and electromechanical responses as large as 5%.
