Thermoelectric properties of inversion symmetry broken Weyl semimetal-Superconductor (WSM-SC) junction

POSTER

Abstract

We theoretically study the thermoelectric properties following the work by of an inversion symmetry broken Weyl semimetal and proximitized superconductor (WSM-SC) junction employing Landauer-Büttiker formalism to noninteracting systems. The study unfolds interesting features of various relevant physical quantities such as thermal conductance, thermoelectric coefficient and figure of merit. Further, we compute the ratio of thermal to electrical conductance in different temperature ranges and found that the Wiedemann-Franz law violates for small temperatures near the Weyl point while saturates to the Lorentz number for metals away from it at all temperatures. Contrasting with other Dirac material hetrostructures, we provide a detailed analysis of the thermal transport in the WSM-SC hetrostructure that would help fabricating mesoscopic thermoelectric devices based on thermoelectric effects.
