Exploring Tantalum as a Potential Dopant to Promote the Thermoelectric Performance of Zinc Oxide

Zinc oxide (ZnO) has being recognised as a potentially interesting thermoelectric material, allowing flexible tuning of the electrical properties by donor doping. This work focuses on the assessment of tantalum doping effects on the relevant structural, microstructural, optical and thermoelectric pr...
