xNZSP-(20−x)Li2O–3Bi2O3–77TeO2 tellurite glass (impedance + RDF analysis)

This record contains the datasets supporting the figures and tables of the associated Physical Review manuscript on xNZSP-(20−x)Li2O–3Bi2O3–77TeO2 glass samples (x = 0–5 mol%). Files include: (i) equivalent-circuit fitting quality metrics (chi-squared, sum of squares), (ii) sample geometry, bulk conductivity and bulk resistance, (iii) RDF peak parameters for Te–O, P–O and Si–O (bond length, intensity, area), (iv) derived average coordination number, average bond length and mixed junction density J(x), and (v) bulk capacitance. Data are provided in CSV format with a README describing columns and units.
