Abstract

We have calculated the electronic structure of the high-temperature super- conductors Bi,Sr2Cu06and TI,Ba,CuO,. We find that the T1-0 layers are mainly covalently bonded,whereastheBi-0 layersalsohaveanioniccomponent.Thesematerialshavevery similar crystal structures, but radically different superconducting properties, T , = 12 K and 90 K respectively. We focus on how ‘metallic’ the Bi/T1 layers are and the degree to which the CuO, layers are doped by charge transfer as possible reasons for this difference, arguing that the latter is dominant.
