This thesis analyzes the thermoelectric properties of anatase at high temperatures, with a special focus on the measurement of electrical resistance and the Seebeck coefficient. Using the two-point method and modulated differential scanning calorimetry, a linear increase in the electrical resistance of anatase with temperature rise was established. This linear increase indicates the degenerate semiconductor nature of anatase. Additionally, a linear increase in the Seebeck coefficient with temperature was observed, which is in line with the theoretical model presented in the work, specifically for semiconductors. The model links the Seebeck coefficient with the effective mass of charge carriers, their concentration, and temperature, where the dependency on temperature is also linear. The results indicate the preservation of the fundamental properties of anatase even at high temperatures and under the influence of the phase transition of the contact thermal paste. The results represent a contribution to the understanding of the thermoelectric behavior of anatase as a thermoelectric, highlighting its potential for use in the development of advanced thermoelectric devices. This analysis paves the way for further research aimed at optimizing anatase as a thermoelectric and developing more efficient thermoelectric materials in general.
