Fig. 4: Pisarenko plot and Hall carrier mobility.

From: Multiple valence bands convergence and strong phonon scattering lead to high thermoelectric performance in p-type PbSe

Fig. 4

a Pisarenko plot of Seebeck coefficients as a function of Hall carrier concentration (nH) for Pb0.98Na0.02Se−x% AgInSe2 (LISS). The solid black line is calculated assuming m* = 0.44me and the purple line represents the result assuming m* = 0.81me within the SPB model. The gray circles show the Pisarenko plot for Na-doped PbSe reported by Wang et al.50. b Hall carrier mobility (μH) versus Hall carrier concentration (nH) at 303 K.
