Description 115-123
ZnO Nanotube with an hcp structure, has been investigated for the transmission of acoustic wave in the 0 to 10 GPA
operating pressure. For this, the Lennard-Jones interaction potential methodology has been utilizing to estimate the
advanced order elastic coefficients (SOECs and TOECs). This model is used to calculate the 2nd and 3rd order elastic
parameters for ZnO Nanotube. Applying SOECs, the additional elastic moduli for ZnO nanotubes, for example the bulk
modulus (B), Young's modulus (Y), as well as shear modulus (G), have been computed. Later, applying SOECs as well as
zincoxide density under the same pressure range, three orientation dependent acoustic velocities, comprising Debye average
velocities, have been studied. Basic thermal characteristics such as specific heat at constant volume (CV), thermal
conductivity k (min) associated with lattice, thermal energy density (E0), thermal relaxation time (𝜏􁈻 as well as acoustic
coupling coefficients (DL, DS) of ZnO Nanotube have been also calculated at same pressure range. Determining the acoustic
attenuation parameters using the method is also successful, arises due to the interaction of phonons, hardness as well as
melting temperature under various pressure in this research work.
