Abstract The existence ofsecond-order structural phase transition in the SnSe at a pressure of10GPa has been proved theoretically. The calculation is performed using the plane-wave pseudopotential approach to density-functional theory within the local-density approximation (LDA) withthe help ofthe ABINIT software package. Theabrupt change inbulk module…
