Continuously controllable photoconductance in freestanding BiFeO3 by the macroscopic flexoelectric effect

Previous methods to generate strain gradient and flexoelectricity are limited to a localized effect or cannot be tuned continuously. Here, the authors achieve macroscale continuously controllable strain gradient in freestanding ferroelectric thin film. Multilevel photoconductance in BiFeO3 films can...
