dc.description.abstract | The synthesis, physicochemical, spectroscopic, and structural characterization of the compound β-K2Bi8Se13 has been previously reported. The results indicated that this material should be investigated further for possible thermoelectric applications. β-K2Bi8Se13 exhibits excellent electrical conductivity values at room temperature while maintaining high Seebeck coefficients. In this work, the optimization of the compound β-K2Bi8Se13 is continued by the introduction of varying concentrations of several different dopants. The value of x in K2Bi8-x SbxSe13 was varied in order to find the composition with minimum thermal conductivity. Where possible, transport measurements were carried out on both single crystal and polycrystalline ingot material. From these data, the trends in the key parameters were identified for optimizing the power factor and figure of merit. | en |
