Abstract
Thermoelectric properties of a-IGZO thin film were optimized by adjusting the carrier concentration. We found that the power factor (PF) has the maximum value of 82 × 10-6 W / mK2 at 300 K, where the carrier density was 7.70 × 1019 cm-3. Additionally, measured data was analyzed by fitting the percolation model. Theoretical analysis revealed that the Fermi level is located on right over the potential barrier when the PF becomes maximum.
