"screened As/Sb elements can facilitate not only the band convergence of light and heavy bands (Delta E(L-Σ)) but also increasing the band gap (Eg) of SnTe, which improved its thermoelectric properties... Ge-Sb or Ge-As co-doping in SnTe is favorable for the improvement of Seebeck coefficients, power factor, and the zT value... SnTe contains toxic-free elements and possesses the high-symmetry rock salt crystal structure"
