“…However, surprisingly, quenching (disorder) led to higher PDP than that of slow cooling wherein S is positive. 27 This matches exactly what are observed in the present Nb samples (Fig. 2).…”

We have reinvestigated the thermopower of group VB metals in polycrystalline forms in the temperature range of 6-300K, taking into account the critical nature of the sample surface and heat treatment especially for niobium. Strikingly small magnitude, negative sign, phonon drag dip and superconductivity not reported previously were observed in surface-cleaned single crystalline Nb. However, while thermopower magnitudes are small, mixed signs were found in the polycrystalline V, Nb and Ta samples. These properties were therefore interpreted as their intrinsic properties and were briefly discussed taking into account of the existing theory by fitting also the data that give the Fermi energies of 10.94 eV, 5.08 eV and 1.86eV, respectively.

“…The measured Δ S data are all within the scope of 1.0–2.2 μV/K (Figure a), showing reliable capability of temperature sensing over the full temperature range. One notes that Δ S first slightly goes down from ≈1.3 μV/K at 302 K to ≈1.0 μV/K at 130 K in the cooling process, then turns to increase when being further cooled, showing a broad hump at ≈130 K, and peaks to ≈2.2 μV/K at ≈25–30 K, finally reduces again when approaching 10 K. This behavior resembles much the drag effect of phonons in metal, which has been well studied in group VB metals (Nb, V, Ta), copper alloys and gold alloys, and Ag–Cd alloys . The phonon‐drag thermopower is ascribed to phonon‐scattering effects.…”
