Simple analytical expressions for the electron band dispersion (p) are obtained within the framework of a tight-binding model. Formulae for the Fermi surface p z = p z ( p x , p y ; E F ) are derived as well. O p ฯ states of the perovskite anion and s state of small cation Bi6s are taken into accoun
