FIG. 1.

(Color online) Temperature dependent (a) electrical resistivity, (b) thermopower in the temperature range 150–600 K. Schematic representation of the distorted band. (a) At T = 300 K, the Fermi levels EF−I, EF−II, EF−III, and EF−IV in samples I, II, III, and IV, respectively, do not align with the enhanced DOS. (b) Above 375 K, the Fermi level in samples I and II moves inside the broadened region of enhanced DOS.

FIG. 2.

(Color online) (a) The plot of thermopower against the electrical resistivity at different temperatures of the samples. (b) Temperature dependent power factor of samples I, II, III, and IV in the temperature range 150–600 K.
