Coexistence of ferroelectric triclinic phases in highly strained BiFeO 3 films

Résumé

Two tilted triclinic phases were found via synchrotron x-ray diffractions in the mixed-phase regions of highly strained BiFeO3 films. First-principles calculations suggest that these two triclinic phases originate from a phase separation of a single monoclinic state accompanied by elastic matching between the two phase-separated states and further suggest that the ease of phase transition between these two energetically close phases is responsible for the large piezoelectric responses observed in Zhang, Nat.
