摘要：

We report the correlation between structural data and transport property, viz, resistivity (rho) and Seebeck Coefficient (Thermopower, S) of n-type thermoelectric material, Bi1-xSbx (0.08 <= x <= 0.20) alloy. Rietveld refinement technique has been used to estimate structural parameters. Thermal variation of rho and S has been measured and the band gap (E-g) of these narrow gap semiconductors has been estimated. Correlation between structural and transport property has been established and dependence of Sb concentration on the Power Factor (PF=S-2/rho) has been revealed.
