The electronic properties of YBa2Cu3O7-δ have been investigated by the energy-pseudopotential method within the local density approximation (LDA) with and without including generalized gradient corrections (GGC). The band structure, density of states and charge density of YBa2Cu3O7- have been calculated. The results are compared with other approaches such as LAPW, LCAO and LMTO for this syste...
