An investigation of thermoelectric power factor of SrBi4Ti4O15and CuO mixed SrBi4Ti4O15

Abstract

In the current article we report the thermoelectric power factor of aurivillius type, SrBi4Ti4O15 and CuO modified SrBi4Ti4O15. It is found that the addition of CuO increased the electric conductivity and thus the power factor of SrBi4Ti4O15. The importance of exploring this material's thermoelectric property originates from its layered structure. The layered structure can be viewed as a phone-glass electron crystal.The maximum value of power factor obtained is 6nWm-1K-2at 6000C for CuO modified SBTi. Research on these family of materials need to be pursued in order to obtain improved values of power factor and thermoelectric efficiency.
