Web27 de nov. de 2024 · The surface oxygen vacancy formation energy (EOvac) is an important parameter in determining the catalytic activity of metal oxides. Estimating these energies can therefore lead to data-driven design of promising catalyst candidates. In the present study, we determine EOvac for various insulating and semiconducting oxides. … WebWe determine the vacancy formation energy and volume as a function of temperature for six FCC metals: Ag, Au, Cu, Ni, Pd and Pt. Our results confirm the validity of treating the vacancy formation energy and volume as constants at intermediate temperatures. Although the temperature dependence of the vacancy formation free energy Web18 de abr. de 2024 · An efficient approach to evaluate the chemical potential in HEA is constructed and implemented. Vacancy formation energies are computed based on the chemical potential. The statistical distribution of formation energies is weakly dependent upon the chemical identity of the vacancy. fitbit charge 5 sleep tracking accuracy
