Electronic structure of the high Tsub(c) superconductor Ba2YCu3Osub(6.9)
Description
The electronic structure of Ba2YCu3Osub(6.9) has been calculated using the linear augmented-plane-wave method. The results show strongly 2-dimensional and 1-dimensional features in the energy bands. These give rise to competing charge density wave instabilities. We argue that the proximity of these instabilities and the large electron-phonon matrix elements of the Fermi-level electrons make important contributions to the high Tsub(c) of this material.
