The ultrasonic properties of terbium monophosphide have been investigated with its mechanical properties along <100>, <110> and <111> orientations. The second and third order elastic constants have also been calculated at 0K - 300K temperatures range using Coulomb and Born-Mayer potential. For finding the stability and ionic nature of TbP, some of the mechanical parameters have also been evaluated at room temperature. Additionally, thermal conductivity is also calculated using Slack's approach. Finally, ultrasonic attenuation in TbP is calculated. Obtained results of the present investigation are discussed in correlation with available results of previous findings.

Abstract


The ultrasonic properties of terbium monophosphide have been investigated with its mechanical properties along <100>, <110> and <111> orientations. The second and third order elastic constants have also been calculated at 0K - 300K temperatures range using Coulomb and Born-Mayer potential. For finding the stability and ionic nature of TbP, some of the mechanical parameters have also been evaluated at room temperature. Additionally, thermal conductivity is also calculated using Slack's approach. Finally, ultrasonic attenuation in TbP is calculated. Obtained results of the present investigation are discussed in correlation with available results of previous findings.
