Based on density functional theory, the structural parameters, elastic moduli and thermophysical properties of Copper-palladium CuPd inter-metallic compound at various temperatures under high pressures have been studied using first-principles calculations. The pseudopotential-plane wave method within generalized gradient approximation approach utilized to perform calculations presented in this paper. material being considered is a pure substance solid CuPd, arranged body centered cubic...
The structural and electronic properties of calcium chalcogenides CaX (X = S,Se,Te) under high pressure have been investigated using the full potential linearized augmented plane wave method within density functional theory. We used both local approximation generalized gradient (GGA) that is based on exchange–correlation energy optimization for calculating total energy. Moreover, Engel–Vosko GGA formalism applied so as to optimize corresponding band structure calculations. equilibrium...
Abstract Structural parameters, elastic constants, electronic band structures, and thermoelectric properties of K 2 ABF 6 (A = Ag, Na, B Rh, Pd, Ni, Nb, Ru, Ti) materials at zero pressure elevated temperatures have been studied. The computations presented within the density functional theory using Cambridge Serial Total Energy Package code. Special attention has given to studied for K‐based double perovskite materials. obtained results are generally found be in good agreement with available...
The outcomes of computational study electronic, magnetic and optical spectra for A2BX6 (A = Rb; B Tc, Pb, Pt, Sn, W, Ir, Ta, Sb, Te, Se, Mo, Mn, Ti, Zr X Cl, Br) materials have been proceeded utilizing Vanderbilt Ultra Soft Pseudo Potential (US-PP) process. Rb2PbBr6 Rb2PbCl6 are found to be a (Г-Г) semiconductors with energy gaps 0.275 1.142 eV, respectively making them promising photovoltaic materials. metallic behavior the Rb2BX6 (B Mo) has confirmed showing attendance conducting...
We present a theoretical investigation of the energy band-gaps and vibrational properties InP1−xSbx semiconducting alloys in zinc-blende structure. For this purpose pseudopotential scheme within virtual crystal approximation that takes into account effects compositional disorder, combined with Harrison bond orbital model are used. In general, our results good agreement available experimental values to few per cent. The absorption at optical gaps indicates material interest is direct Γ...
