P. Alpay, N. Q. Vinh, and Shashank Priya We report the dynamics of soft phonon modes and their role toward various structural transformations in Aurivillius materials by employing terahertz frequency-domain spectroscopy, atomic pair distribution function analysis, and first-principles calculations. We have chosen B i 4 T i 3 O 12 as a model syste... [Phys. Rev. B 96, 134114] Published Wed Oct 18, 2017
