Nanosecond Phase Transition Dynamics in Compressively Strained Epitaxial BiFeO3
Margaret P. Cosgriff, Pice Chen, Sung Su Lee +11
A highly strained BiFeO3 (BFO) thin film is transformed between phases with distinct structures and properties by nanosecond-duration applied electric field pulses. Time-resolved s…

Giant optical enhancement of strain gradient in ferroelectric thin films and its physics origin
Yuelin Li, Carolina Adamo, Pice Chen +9
The coupling between strain gradients and polarization, known as flexoelectricity, offers a new mechanism to control the functionality of dielectric materials. However, for the eff…
