Magistrsko delo

Oznake: Density Functional Theory;first-principle calculations;Mg surface;Surface Core-Level Shift;surface relaxation;surface reconstruction;

In this work, three surfaces, namely, Mg(0001), Mg(10 ̄1 0) and Mg(11 ̄2 0) are investigated by means of Density Functional Theory and Generalized Gradient Approximation first-principle calculations. The surfaces have been characterized in terms of their interlayer distances, surface energies, Pro ...
