Abstract
We present here a thermoelectric transport property study of Bi1-xSbx alloy nanowires embedded in a dielectric matrix. Temperature-dependent resistance measurements exhibit non-monotonic trends as the antimony mole fraction (x) increases, and a theoretical model is presented to explain the features that are related to the unusual band structure of Bi1-xSbx systems. Seebeck coefficient measurements are performed on nanowires with different diameters and compositions, showing enhanced thermopower over bulk Bi. The magneto-Seebeck coefficient of these nanowires also exhibits an unusual field dependence that is absent in bulk samples.
