Non-universal Scaling of Thermoelectric Efficiency in 3D and 2D Thermoelectric Semiconductors

Kevin Octavian, Eddwi H. Hasdeo

We performed the first-principles calculation on common thermoelectric semiconductors $\mathrm{B}{\mathrm{i}}_2\mathrm{T}{\mathrm{e}}_3$, $\mathrm{B}{\mathrm{i}}_2\mathrm{S}{\mathrm{e}}_3$, $\mathrm{SiGe}$, and $\mathrm{PbTe}$ in bulk three-dimension (3D) and tw…
