Computational Materials


A parametric study concerning the U value in the framework of the DFT+U method was undertaken to determine the best U value for almost all transition metals and some rare earths regarding their most stable structure/phase and their respective simplest oxide. An open access "computational materials" database was created including lattice parameters, atomic partial magnetic moment, band gap and heat of formation of the selected U values along with their literature data provided for comparative reasons. This database is a useful tool in order to “synthesize” the computational parameters of complex mixed metal oxides for fast materials investigation and screening purposes.
