Strain-Induced Antiferroelectric-Ferroelectric-Antiferroelectric Phase Transitions in Epitaxial LaTaO 4 Films

We employed first-principles to delve into the strain-induced structural phase transitions in epitaxial LaTaO films. The ground state of bulk LaTaO adopts a monoclinic antiferroelectric phase, characterized by the antiphase rotation of two adjacent oxygen octahedra layers. Under epitaxial tensile st...
