Ultrasonic and Thermophysical Properties of Cobalt Nanowires

We have estimated elastic, mechanical, thermal and ultrasonic properties, in high temperature regime, of cobalt nanowires (Co-NWs) having a hexagonal close-packed (HCP) structure. The second and third order elastic constants (SOECs and TOECs) have been calculated using the Lennard–Jones potential mo...

description We have estimated elastic, mechanical, thermal and ultrasonic properties, in high temperature regime, of cobalt nanowires (Co-NWs) having a hexagonal close-packed (HCP) structure. The second and third order elastic constants (SOECs and TOECs) have been calculated using the Lennard–Jones potential model at 300 K. These elastic constants are used to find out mechanical properties, ultrasonic velocities, Grüneisen parameters and thermal conductivity of Co-NWs. Further, these properties are used to analyze the stability and bonding properties of the present system. The relaxation time, non-linearity parameter and ultrasonic attenuation have been computed using the associated parameters. The achieved results of the present investigation have been analyzed with other NWs systems .
