The effect of temperature and pressure on some thermodynamic characteristics of fcc structural copper metal
Main Article Content
Abstract
In this study, we used a semi-empirical method based on an unharmonic correlated Debye model to investigate the temperature and pressure dependence of thermodynamic quantities including Debye frequency, Debye temperature, and Debye–Waller coefficient of FCC-structured copper. Numerical calculations for Debye frequency and Debye temperature were performed up to a pressure of 450 GPa, and for DWF at temperatures up to 1000 K and a pressure of 50 GPa using Morse interaction potentials with parameters derived from the inverse Möbius crystal lattice scheme. The results obtained show good agreement with experimental data and previous theoretical publications, contributing to the database and providing useful information for the application of this material in scientific and technological fields.
