Dual-functional Bi2Se3 incorporation enables synergistic optimization of carrier and phonon transport in n-type PbS

Lead sulfide (PbS) is a promising mid-temperature thermoelectric material; however, its performance is constrained by the difficulty of simultaneously optimizing electrical transport and suppressing lattice thermal conductivity. Herein, a Bi2Se3 incorporation strategy is developed to synergistically regulate carrier an...
