. None of the resistive anomalies typical of materials transitioning to a state with a chargedensity wave are observed; neither are any of the signs of a superconducting state transition (at least down to a temperature of 8 K). Band calculations confirm that states near the Fermi level are formed and reveal the structure of the valence and conduction bands. |
