Witrynaimpurities moved perpendicular to the dislocation line. Ab initio calculations of the total energy and the elec-tronic structure of this supercell were performed for each impurity position. The calculations were based on the density functional theory in the general gradient approximation using the ABINIT software package [8]. http://www.elektron.up.krakow.pl/ab/1110.0717.pdf

The effect of progressively replacing Mg by Ni or similar cations (Co, Cu ) on the surface properties has been investigated both experimentally [111, 163,164] and theoretically [165,166]. … Witrynareplacing iron atom. Perturbations due to single impurity could be seen to the second or third coordination shell depending on the impurity [2–4]. This work reports ab initio investigations of impurity effect on the charge and spin densities on the iron nucleus. First principles studies were performed for impurities located at some definitive fishers chemist
