  • Electronic structure of C60simple cubic phase by full-potential mixed-basis band calculation

    • 摘要:

      An electronic structure calculation with full-potential and all-electron ab initio formalism is performed for hypothetical low-temperature simple cubic phases (Pn3 and Pa3 space groups) of C60molecular crystal, in which every molecule is orientationally freezed. The degeneracies at special k-points, the magnitudes of energy gaps, and the widths of bands have been found to be sensitive to the orientation of the fullerenes in the crystal. Our result suggests that the structure with Pa3 space group with -22° rotation around [111] directions, which David et al. proposed, is more stable compared to the structure with Pn3 space group with the same rotation angle.
