Figure 7

The 7-Chebyshev-node interpolation of measured and simulated TEPs for the nanostructured Bi-Sb-Te bulk alloys in18: (left) Seebeck coefficient, (center) electrical resistivity, (right) thermal conductivity. The red dots denote the raw data points in18. The blue dots denote the simulated TEPs using the Boltzmann transport equations with the relaxation time approximation within first-principles calculations. Both are well interpolated by 7 Chebyshev nodes. The details of the simulation method are given in SI.
