Abstract

First principles calculations predict the promising thermoelectric material ZnGeSb₂with a huge power factor (S²σ/τ) on the order of 3 × 10¹⁷W m⁻¹K⁻²s⁻¹, due to the ultra-high electrical conductivity scaled by a relaxation time of around 8.5 × 10²⁵Ω⁻¹m⁻¹s⁻¹, observed in its massive Dirac state.
