Elastic and Ultrasonic Properties of LaPn (Pn=N, P, As, Sb, Bi)
Elastic and ultrasonic properties of lanthanum pnictides (LaPn) have been investigated along <100>, <110>, <111> directions in the temperature range 100K to 300K. The second and third order elastic constants (SOECs and TOECs) have been computed using Coulomb and Born-Mayer potential using nearest neighbour distance and hardness parameter. Other parameters like Young's modulus, bulk modulus, shear modulus, Zener anisotropic factor, Poisson's ratio, toughness to fracture (G/B) ratio have also been found out for the future performance of LaPn. Additionally ultrasonic velocity has been evaluated with use of SOECs and TOECs. Obtained results are discussed in correlation with available mechanical and thermophysical properties of these materials.
