Strongly reduced lattice thermal conductivity in Sn-doped rare-earth (M) filled skutterudites M x Co 4 Sb 12−y Sn y , promoted by Sb–Sn disordering and phase segregation

Year: 2021

Type: article

Abstract: Three effects act as phonon scatterers: rattling of M at 8 a cages, phase segregation, and intrinsic disorder introduced by Sn substitution, resulting in minimum k values. High filling fraction in Sn-doped phases pave the way to tune the carrier density in skutterudites.
