    • 1/(n+1)] the exponent 1/(n+1) can be determined by the slope of the log[d log(ρ)/d log(1/T)] vs log(T) plot (see Refs. 15 and 38). In our fitting processes of Mott VRH and E-S VRH, we made sure that the exponent values should be same with the slopes in those plots. And with additional 1/√T and 1/T terms (see Refs. 33 and 37), we could get better fitting curves.

    • note
    • In this complex system with both disorder and correlation effects, the conductivity maximum energy is not simply determined. Particulary in the small x region, the electron correlation should also involve in this conductivity maximum behavior (see Ref. 12).

    • While the Coulomb interactions are given in a various way under the consideration of the multiplicity effect in the orbitally degenerate Hubbard model, the U value here corresponds to the multiplet-averaged Coulomb interaction.
