Tight-binding parametrization of first-principles electronic dispersion in orientationally disordered [ital A][sub 3]C[sub 60]

We derive numerical tight-binding hopping parameters to describe conduction-band dispersion in arbitrary orientational phases of [ital A][sub 3]C[sub 60]. The parameters are obtained by direct Fourier inversion of the spectra from self-consistent electronic-structure calculations for K[sub 3]C[sub 6...
