FIG. 1.

(a) Crystal structure for SBN showing the connectivity of the octahedra. A-site: Sr, B-site: Sr or Ba, and C-site: vacant site. (b) Seebeck coefficients as a function of temperature for SBN [ (A, B, C, and D) and (, , and )] single crystals annealed at under various conditions. Samples A, B, C, and D were measured parallel to the c-axis, and samples , , and were measured perpendicular to the c-axis.

FIG. 2.

(a) Plot of vs and vs and (b) and (c) activation energies for carrier generation and mobility as a function of reduction degree for samples A, B, C, and D.

Image of FIG. 3.
FIG. 3.

Power factor as a function of temperature for samples A, B, C, D, and . The dotted region in sample B is estimated assuming a continuous increase of electrical conductivity from the up to 516 K.
