摘要：

Engineering the molybdenum disulfide (MoS2) and reduced graphene oxide hybrid via layer-by-layer stacking is an efficient way to enhance the thermoelectric performance by decoupling the Seebeck coefficient and electrical transport. The fabricated MG achieved maximum of -25.2 mu V K-1 at 325 K, 23.5 S m(-1) at 351 K, and 15.5 nW m(-1) K-2 at 325 K for the Seebeck coefficient, electrical conductivity, and power factor, respectively. The pi-pi interactions at the interface of MoS2-rGO, where the low charge carriers (cold electrons) are scattered without affecting the mobility, simultaneously enhanced the thermoelectric performance through the decoupled Seebeck coefficient and electrical conductivity.
