Self-consistent band structure for β-(BEDTTTF)₂I₃

Preliminary results of a self-consistent electronic band structure calculation for β-(BEDTTTF)₂I₃ are presented. The calculations are based on the local density functional approximation and the ASW-algorithm. Energy bands and the topology of the Fermi surface are determined and, by means of partial densities of states, the origin of the various states near the Fermi level is elucidated. The high value of the superconducting transition temperature is discussed qualitatively.
