Nanosecond Optically Induced Phase Transformation in Compressively Strained BiFeO3 on LaAlO3
Youngjun Ahn, Anastasios Pateras, Samuel D. Marks +9
Above-bandgap optical illumination induces a transformation from tilted tetragonal-like (T-like) and rhombohedral-like (R-like) phases to an untilted T-like phase in compressively…
