Thermoelectrics: From Bonding Asymmetry to Anharmonic Rattling in Cu12Sb4S13 Tetrahedrites: When Lone‐Pair Electrons Are Not So Lonely (Adv. Funct. Mater. 24/2015)
Year: 2015
Type: article
Abstract: Tetrahedrites were recently discovered to be high-performance thermoelectrics but the chemical and structural origins of the rattling guests and resultant low thermal conductivity remain elusive. On page 3648, W. La and team establish a clear connection between the local bonding asymmetry and anharmonic rattling modes in Cu12Sb4S13 tetrahedrites, enabled by the chemically active electron lone pairs.
