The calculation model is derived from the anharmonic correlated Debye (ACD) model that is developed using the many-body perturbation approach and correlated Debye model based on the anharmonic effective potential. This potential has taken into account the influence on the absorbing and backscattering atoms of all their nearest neighbors in the crystal lattice. The numerical results for the crystalline zinc (Zn) and crystalline copper (Cu) are in agreement with those obtained by the other theoretical model and experiments at several temperatures. The analytical results show that the ACD model is useful and efficient in analyzing the TE of coefficient of metal crystals.</p>}, number={1}, journal={Advances in Technology Innovation}, author={Tong Sy Tien and Nguyen Thi Minh Thuy and Vu Thi Kim Lien and Nguyen Thi Ngoc Anh and Do Ngọc Bich and Le Quang Thanh}, year={2023}, month={Jan.}, pages={73–80} }
