Enhancing the Thermoelectric Properties of Misfit Layered Sulfides (MS)1.2+q (NbS2) n (M = Gd and Dy) through Structural Evolution and Compositional Tuning.

ABSTRACT: The misfit monolayered sulfides, (GdS)1.20NbS2, (DyS)1.22NbS2, (Gd0.1Dy0.9S)1.21NbS2, (Gd0.2Dy0.8S)1.21NbS2, and (Gd0.5Dy0.5S)1.21NbS2 and the misfit bilayered sulfide (GdS)0.60NbS2 were synthesized via sulfurization under flowing CS2/H2S gas and consolidated by pressure-assisted sintering. The thermoelectric properties of the monolayered and bilayered sulfides perpendicular (in-plane) and parallel (out-of-plane) to the pressing direction were investigated over a temperature range of 300-873 K. The crystal grains in all the sintered samples were preferentially oriented perp
