Abstract:

First-principles calculations are employed to predict the thermoelectric properties of the 2D materials Ti₂CO₂, Zr₂CO₂, and Hf₂CO₂ in order to evaluate the role of the metal atom. Flat conduction bands are found to promote the thermopower in the case of n-doping. The lattice thermal conductivity is demonstrated to grow along the series Ti-Zr-Hf in the temperature range 300-700 K, resulting in the highest figure of merit in the case of Ti₂CO₂.
