Title: | Influence of the charge concentration on the density of states in a two-dimensional superconducting system |
Authors: | Orozco, S Ortiz, MA Mendez-Moreno, RM Moreno, M |
Issue Date: | 2007 |
Abstract: | The gap and the density of states of high-T-c superconductors have been a subject of paramount interest. In order to explain the observed experimental behavior several pairing mechanisms in high-temperature superconductivity have been considered, by theoretical calculations. In this work, within the BCS scheme, a two-band model with energy band overlapping is introduced. The gap parameter and the density of states in a two-dimensional superconducting system are studied as functions of the charge concentration. This model is applied to Bi2212 in order to obtain numerical results. (C) 2007 Elsevier B.V. All rights reserved. |
