Group Theory Analysis to Study Phase Transitions of Quasi-2D Sr<sub>3</sub>Hf<sub>2</sub>O<sub>7</sub>

Group Theory Analysis to Study Phase Transitions of Quasi-2D Sr<sub>3</sub>Hf<sub>2</sub>O<sub>7</sub>

We present an <i>ab-initio</i> study performed in the framework of density functional theory, group-subgroup symmetry analysis and lattice dynamics, to probe the octahedral distortions, which occur during the structural phase transitions of the quasi-2D layered perovskite Sr<sub>3&...
