Atomic disordering was an effective strategy to reduce lattice thermal conductivity. In this work, the atomic disordering of Mg2-δSn1-xBix was maximized by both the charge self-compensation and steric effects. Due to the strong phonon scattering arose from substitutional defects BiSn and self-compen...
