Abstract
An in-depth structural study of a 23-nm-thick BiFeO3 film grown on orthorhombic NdScO3(110)O substrates demonstrates the presence of a mixed phases. Atomic resolution scanning transmission electron microscopy measurements reveal an out-of-plane stripe domain structure typical of rhombohedral BiFeO3 films but with a polarization component along pseudocubic ⟨100⟩PC or canted from the ⟨111⟩PC towards the in-plane direction. Photovoltaic measurements display an anomalous modulation of the open circuit voltage as temperature is decreased that is attributed to a structural change associated with a transition to a single structural phase.
