Abstract
First principle calculations have been performed to study the lattice vibration of BaX2 (X = Si, Ge). A rigid-unit vibrational mode has been observed, and this mode confines and scatters acoustic phonon modes, leading to a low thermal conductivity. Their stability is analyzed from the calculations of thermodynamic properties.
