Phase stability of ScN-based solid solutions for thermoelectric applications from first-principles calculations

Automating First-Principles Phase Diagram Calculations

Devising a computational tool that assesses the thermodynamic stability of materials is among the most important steps required to build a “virtual laboratory”, where materials could be designed from first-principles without relying on experimental input. Although the formalism that allows the calculation of solid state phase diagrams from first principles is well established, its practical imp...

Phase stability in the Fe–Ni system: Investigation by first-principles calculations and atomistic simulations

First-principles calculations of the energy of various crystal structures of Fe, Ni and ordered Fe–Ni compounds with different stoichiometries have been performed by the linearized augmented plane wave (LAPW) method in the generalized gradient approximation. The most stable compounds are L12–Ni3Fe, L10–FeNi, C11f–Ni2Fe and C11f–Fe2Ni. The L12–Ni3Fe compound has the largest negative formation en...
