Baquero Física, Astronomía y Matemáticas Bi Bi 2223 2223 Fermi surface The displacements effects of the oxygen atom associated to the Sr-plane (O3) in the electronic properties of Bi2Sr2Ca2Cu3O10 (Bi-2223), have been investigated using density functional theory. We determined intervals of the O3 atomic positions for which the band structure calculations show that the Bi-O bands, around the high symmetry point M in the irreducible Brillouin zone, emerge towards higher energies avoiding its contribution at Fermi level, as experimentally has been reported. This procedure does not introduce foreign doping elements into the calculation. Our calculations present a good agreement with the angle-resolved photoemission spectroscopy (ARPES) and nuclear magnetic resonance (NMR) experiments. The two options found differ in character (metallic or nonmetallic) of the Bi-O plane. There are not any experiments, to the best of our knowledge, which determine this character for Bi-2223. 2015 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57036862004 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
