Abstract :
Temperature-dependent resistance and Seebeck coefficient measurements were performed on Bi1-xSbx nanowire arrays with various wire diameters and Sb contents. The results showed enhanced thermopower and complex R(T) behavior due to the unique semimetal-to-semiconductor transition predicted for Bi-related nanowire systems. The agreement between theoretical calculations and experimental results not only supports the model we used, but also validates the promising thermoelectric properties predicted for Bi1-xSbx nanowire systems.
