摘要： The delicate balance between elastic energy and electrostatic energy in highly strained BiFeO3 (BFO) thin films results in complex mixed-phase patterns, which poses significant challenges for theoretical understanding and complicates the realization of its full potential in magnetoelectric, electromechanical, and photovoltaic devices. In this letter, we explore in-plane electric field induced phase transition in strain engineered BFO thin films and elucidate the mechanism behind the assembly behavior of complex nano-scale phase domains. Our approach enables deterministic control of phase variants with well-defined structures and orientation, paving the way for designing novel data storage devices based on mixed phase BFO. 出版日期： 2012-09-15 出處： Journal of applied physics, 2012-09, Vol.112 (6) 資源來源： AIP Journals (American Institute of Physics) 識別號： ISSN: 0021-8979 識別號： ISSN: 1089-7550 識別號： ISSN: 1520-8850 識別號： EISSN: 1089-7550 識別號： DOI: 10.1063/1.4752395
