Noncentrosymmetric structural transitions in ultrashort ferroelectric AGaO${}_3$/A'GaO${}_3$ superlattices

Nayoung Song, James M. Rondinelli, Bog G. Kim

The effect of octahedral tilting on the acentric structural transitions in AGaO${}_3$/A'GaO${}_3$ [001], [110], and [111] superlattices (A, A' = La, Pr, Nd) is studied using densit…
