Web[en] Numerical simulation based on first-principle calculations is applied to study the wurtzite Al x In 1-x N. Simulation results suggest that the Vegard's law deviation parameter is 0.063±0.014 Aa for the a lattice constant, and -0.160±0.015 A for the c lattice constant. The band gap bowing parameter is 3.668 ±0.147 eV with the lattice constants by means of … A method is proposed for calculating the lattice parameter (l) for the solid solution … Cationic and anionic concentration dependent elastic properties of zinc …
WebThe substituted apatites Ca10(PO4)6(1−x)(VO4)6x (OH)2 and Pb10(PO4)6(1−x)(VO4)6x (OH)2, where x is the fraction of vanadate, were prepared in the powdered microcrystalline nature. The X-ray diffraction patterns and the infrared spectra of these substituted apatites were recorded. The analysis of the measurements established that the unit cell …
WebSep 26, 2024 · In view of contradictory prior results, a critical analysis of this method has been carried out, with emphasis on nonlinear elasticity corrections and systematic errors in popular RBS simulation codes. The approach followed is validated by showing that measurements of Ge 1-x Si x films yield a bowing parameter θ GeSi 1-y Sn y alloy films, … WebImportantly, we establish a simple relationship linking the relative size of the group III atoms in the alloy and the predicted magnitude of the deviation from Vegard’s law. AB - Vegard’s law states that, at a constant temperature, the volume of an alloy can be determined from a linear interpolation of its constituent’s volumes.
WebJul 15, 2004 · In this work, by means of numerical simulation based on first-principles calculations, we first investigated the deviation of the zincblende In x Ga 1−x N lattice constants from Vegard's law. The bowing parameter obtained with the equilibrium lattice constants and that obtained with the lattice constants derived from Vegard's law are …
