The specific heat has been measured at low temperatures (∼ 1°K to 20°K) for four large crystals of VCx, with results that indicate the presence of maxima near x=0.85 in both the Debye characteristic temperature, θ0, and the electronic density of states at the Fermi level Nγ(ζ). The behaviour of θ0 suggests that the maximum melting temperature of VCx occurs at a composition close to that of the ordered compound V6C5, rather than at the composition VC0.75 proposed recently by Rudy. The variation of Nγ(ζ) with x has been used to obtain an estimate for the density-of-states curve in the vicinity of the Fermi level. The result is discussed in terms of the behaviour expected from elementary considerations of the electronic structure. |
