摘要：

We investigate the charge redistribution in high T-c cuprates as a function of pressure, composition, and doping. To this extent we have performed first-principles calculations based on density functional theory for several representatives of the Hg based cuprates. In particular, we focus on the creation of holes in the copper-oxygen planes. Conclusions are drawn about the similarities and differences between the three parameters influencing the superconducting transition temperature. (C) 2004 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
