Özet
A theoretical study of structural, electronic, elastic and phonon properties of NaZnX (X = P, As and Sb) compounds is presented by performing ab initio calculations based on density-functional theory using the full-potential linear augmented plane wave (FP-LAPW) and pseudopotential plane wave method. The generalized-gradient approximation (GGA) and the local density approximation (LDA) are chosen for the exchange–correlation energy. The Engel-Vosko (EVGGA) formalism is applied for electronic properties. The calculated structural parameters, such as the lattice constant, bulk modulus, second-order elastic constants, the electronic band structures and the related total density of states and charge density are presented. The high-pressure α or β phase of all compounds is investigated and phase transition pressure from tetragonal to high-pressure phase is determined. We have found that the Nowotny–Juza …
