We have investigated the origins of ultralow thermal conductivity behavior in Ag8XSe6 (X = Si, Ge, and Sn) argyrodites compounds in orthorhombic Pmn21 structure by exploring mechanical and lattice dynamical properties using ...

In this work, we have examined the structural, phonon and anisotropic elastic properties of a hexagonal δ-WN compound via density functional theory. The obtained structural parameters and mechanical properties are in ...
