Flexoelectric control of defect formation and associated electronic function is demonstrated in ferroelectric BiFeO 3 thin films. An intriguing, so far never demonstrated, effect of internal electric field ( E int ) on defect formation is explored by a means of flexoelectricity. Our study provides novel insight into defect engineering, as well as allows a pathway to design defect configuration and associated electronic function.
