摘要: Based on the EHMO approach, an approximate treatment of electronic energy-band structures is suggested. By employing this treatment, computations band for Al-doped superconductors YBa2Cu3–xAlxO7 + δ were carried out. It shown by analysis and density states that 2D Cu–O planes in YBa–CuO superconducting system play a dominant role superconductivity, whereas 1D CuO ribbons have indirectly influence superconductivity through connection O(4) atoms to two planes. © 1994 John Wiley & Sons, Inc.
