Vibrational-Anharmonicity-Assisted Phase Transitions in Perovskite Oxides by pooja is a document available to read on EtoBox.
The study investigates phase transitions in perovskite oxides, specifically PbTiO3 and BaTiO3, under terahertz (THz) irradiation, utilizing optical susceptibility to analyze Gibbs free-energy variations. The findings reveal that intermediate THz light can induce polarization changes and phase transitions at room temperature, highlighting the significant role of anharmonic vibrations. The research suggests a novel, energy-efficient method for controlling phase transitions in these materials, which could have
