Catlow, Atsushi Togo, and Isao Tanaka The layered semiconductor SnSe is one of the highest-performing thermoelectric materials known. We demonstrate, through a first-principles lattice-dynamics study, that the high-temperature C m c m phase is a dynamic average over lower-symmetry minima separated by very small energetic barriers. Compared… [Phys. Rev. Lett. 117, 075502] Published Wed Aug 10, 2016
