Abstract: Using first-principles calculations we examine the crystal structures and phase transitions of nitride perovskite ${\mathrm{LaWN}}_{3}$. Lattice dynamics calculations indicate that the ground-state structure belongs to space group $R3c$. Two competitive phase transition pathways are identified… read more here.
