Giant optical enhancement of strain gradient in ferroelectric BiFeO(3) thin films and its physical origin
Through mapping of the spatiotemporal strain profile in ferroelectric BiFeO(3) epitaxial thin films, we report an optically initiated dynamic enhancement of the strain gradient of 10(5)–10(6) m(−1) that lasts up to a few ns depending on the film thickness. Correlating with transient optical absorpti...
