We report a density functional theory investigation of the electronic structure of a monolayer of Na adsorbed on a Cu(111) substrate. We approach this problem by taking into account a truly semi-infinite substrate within the embedding Green function

In this multicenter, retrospective study of 160 brain biopsies in the assessment of HN-related focal brain lesions, diagnostic sensitivity was acceptable (87%), but the procedure carried considerable morbidity (7.5%) and mortality (3.1%). Moreover, i

We studied a quantum-well state (QWS) generated by the adsorption of one monolayer of K on Cu(111) surface by means of a first principles approach. We calculated the electronic properties of the system within the Inglesfield’s embedding method, whi

The system p(2x2)-Cs/Cu(111) reveals a manifold of surface localized electronic states, such as image states, quantum well states, and surface resonances. We find an electronic state with a band energy above the vacuum level while strictly localized
