Influence of Temperature-Dependent Thomson Coefficient on Thermal Transport in a Low-Dimensional Nanostructure

The Thomson effect heats or cools a material when a current passes along its length in the presence of a temperature gradient ∇T. It is typically neglected in analyses of thermoelectric cooling because the Thomson coefficient Γ(T), which is related to the temperature dependence of the Seebeck coefficient S(T), is ignored. We investigated the influence of (1) and on an intrinsic Si nanowire cooler and found that the temperature dependence of …
