Abstract
Behavior consistent with Coulomb-mediated high- T C superconductivity is shown to be present in the intercalated group-4-metal nitride halides A x (S) y MNX, where the MNX host (M = Ti, Zr, Hf; X = Cl, Br) is partially intercalated with cations A x and optionally molecular species (S) y in the van der Waals gap between the halide X layers, expanding the basal-plane spacing d. The optimal transition temperature is modeled by T C0 ∝ ζ −1(σ/ A)1/2, where the participating fractional charge per area per formula unit σ/A and the distance ζ, given by the transverse A x -X separation (ζ < d), govern the interlayer Coulomb coupling. From experiment results for β-form compounds based on Zr and Hf, in which concentrations x of A x are varied, it is shown that σ = γ[ v(x opt − x 0)], where x opt is the optimal doping, x 0 is the onset of superconducting behavior, v is the A x charge state, and γ = 1/8 is a factor determined by the model. Observations of T C < T C0 in the comparatively more disordered α-A x (S) y TiNX compounds are modeled as pair breaking by remote Coulomb scattering from the A x cations, which attenuates exponentially with increasing ζ. The T C0 values calculated for nine A x (S) y MNCl compounds, shown to be optimal, agree with the measured T C to within experimental error. The model for T C0 is also found to be consistent with the absence of high- T C characteristics for A x MNX compounds in which a spatially separated intercalation layer is not formed.
