Using a facile doping strategy, the thermoelectric performance of tungsten disulfide is enhanced up to 70 times. Our study will stimulate further exploration of the potential applications in thermoelectrics for transition metal dichalcogenide semiconductors and other two-dimensional materials.
Hierarchical microstructures lead to high thermoelectric performance in Cum+nPb100SbmTe100Se2m (CLAST) through synergistically optimizing carrier and phonon transport.
