Abstract: Thermoelectric (TE) parameters follow a counterbalanced interdependence that poses a native barrier towards TE applications. Two-dimensional transition metal dichalcogenides (2D-TMDs) have garnered immense interest as promising TE materials owing to their discretization of density-of-states and tunability of electronic and optical properties. New theoretical insights and novel experimental techniques have empowered recent developments in TE physics and performance, providing new pathways to weaken the counterbalanced interdependency. While 2D-TMDs are predicted to exhibit superior TE performance, experimental realization is hindered by the complexity of TE transport. This thesis investigates the charge transport and interactions on TE transport in 2D-TMDs via three approaches: (1) active phase engineering, (2) substrate-induced non-uniform strain and (3) interlayer excitons; and elucidates their underlying physics and scattering mechanism as well as their viability in decoupling the counterbalanced interdependency for enhancing TE performance.
