    Abstract

    In this study, thermal-treatment-derived variations of the thermoelectric characteristics of ZnO nanofibers (NFs) are examined. NFs that were prepared by electrospinning were transformed into n-type ZnO NFs after they were exposed to thermal heating for 30 min at 550°C. For the ZnO NFs, the Seebeck coefficient decreased from - 132.1 µV/K to - 44.6 µV/K over the heating-time range of 30 min to 120 min, while the electrical conductivity increased from 2.07 × 10-3 S/ m to 0.18 S/m.
