Improvement of MoS2 thermoelectric power factor by doping WSe2 nanoparticle

Twist-Angle-Dependent Phonon Transport of van der Waals MoSe2 Thermoelectric Materials for the Recycling of Waste Heat

“…As a novel category of layered materials, 2D transition-metal dichalcogenides (TMDCs), which can be expressed as MX 2 (M = Mo, W, Ti, and X = S, Se, Te), have been proven to be ideal candidates for advanced thermoelectric materials due to their relatively high electrical conductivity, low thermal conductivity, high Seebeck coefficient, and wide tunability of the inherent thermoelectric parameters. − Except for the way of adjusting thermal conductivity, such as porosity design, , doping, grain refinement, , and defects, , weak van der Waals (vdW) connections between layers make interlayer twist a reliable approach for regulating the thermal conductivity of layered 2D materials. − Di Battista et al demonstrated that the magic-angle twisted bilayer graphene can obtain the coexistence of ultralow electronic heat capacity, thermal conductance, and carrier density. Cheng et al discovered that different stacking modes of twisted graphene produce phonon scattering sites that lower the thermal conductivity.…”
