Abstract

In this study, the influence of titanium oxide (TiO2) dopants and varying calcination processes on the thermoelectric properties of CuCrO2 was systematically explored. It was emphasized that these factors were not only affecting dislocation density but also exerting a profound influence on thermoelectric performance through the modulation of Seebeck coefficient and resistivity. The findings highlighted CrT-2, which incorporated TiO2 and underwent a two-time calcination process, as the top-performing sample in terms of power factor values, underscoring the significance of TiO2 as a dopant for enhancing thermoelectric efficiency. Conversely, Cr-4, exposed to four calcination cycles, exhibited slightly lower power factor values compared to Cr-2. Notably, CrT-4, despite containing the titanium dopant, showed the lowest power factor values, potentially due to intricate interactions between the dopant and the extended calcination process. These results underscore the intricate interplay between dopants, calcination processes, and thermoelectric performance in CuCrO2, necessitating precise optimization to achieve the desired material efficiency.
