Author(s): Christopher D. O'Neill, Dmitry A. Sokolov, Andreas Hermann, Alexei Bossak, Christopher Stock, and Andrew D. Huxley We report that the lowest energy transverse-optic phonon in metallic SnTe softens to near zero energy at the structural transition at T C = 75 K and importantly show that the energy of this mode below T C increases as the temperature decreases. Since the mode is a polar displacement this proves unambiguo… [Phys. Rev. B 95, 144101] Published Mon Apr 03, 2017
