The internal electric field of ferroelectric materials originated from its spontaneous
polarization can effectively improve the efficiency of carrier separation. Heterostructure …

The photocatalytic and dielectric behaviors of Aurivillius oxyfluorides such as Bi2TiO4F2
depend sensitively on their crystal structure and symmetry but these are not fully understood …

Aurivillius oxyfluoride perovskites exhibit great potential in photocatalysis, which are
generally prepared by high-temperature solid-state reactions and some impurity phases are …

Aurivillius oxides have been a research focus due to their ferroelectric properties, but by
replacing oxide ions by fluoride, divalent magnetic cations can be introduced, giving Bi2 M …

We explore the effect of anion ordering on the ferroelectric properties of the oxyfluoride
Aurivillius Bi 2 TiO 4 F 2 from first-principles calculations. We first identify the phonon …
