Fig. 4: Scattering rate ratios (converged versus 0.1 eV offset) of CaZnMgSb2 at 600 K.
From: When band convergence is not beneficial for thermoelectrics
A value above (below) unity indicates that scattering increases (decreases) due to convergence. The energy scale is zero-referenced to the VBM. a The overall scattering rate ratio. b The DPS ratio, whereby the upper band only increases in scattering, while the lower band only decreases in scattering. c The POS ratio, whereby both bands increase in scattering past the emission onset.
