چکیده
We theoretically investigate the thermoelectric properties (electronic contribution) of a hybrid structure comprising an inversion symmetry broken Weyl semimetal (WSM) and intrinsic superconductor (WSC) with $s$-wave pairing, employing Blonder-Tinkham-Klapwijk formulation for noninteracting electrons. Our study unfolds interesting features various relevant physical quantities such as thermal conductance, coefficient, corresponding figure merit. also explore effects interfacial insulating (I) barrier (WSM-I-WSC setup) on response in thin limit. Further, we compute ratio to electrical conductance different temperature regimes find that Wiedemann-Franz law is violated small temperatures (below critical ${T}_{c}$) near points while it saturates Lorentz number, away from points, at all irrespective strength. compare contrast this behavior other Dirac material heterostructures provide detailed analysis transport. can facilitate fabrication mesoscopic devices based WSMs.

Nonlinear thermoelectric effects in high-field superconductor-ferromagnet tunnel junctions
Background: Thermoelectric effects result from the coupling of charge and heat transport and can be used for thermometry, cooling and harvesting of thermal energy. The microscopic origin of thermoelectric effects is a broken electron-hole symmetry, which is usually quite small in metal structures. In addition, thermoelectric effects decrease towards low temperatures, which usually makes them va...

Probing Electronic and Thermoelectric Properties of Single Molecule Junctions Jonathan R. Widawsky In an effort to further understand electronic and thermoelectric phenomenon at the nanometer scale, we have studied the transport properties of single molecule junctions. To carry out these transport measurements, we use the scanning tunneling microscope-break junction (STM-BJ) technique, which in...
متن کاملFunctional superconductor interfaces from broken time-reversal symmetry.
The breaking of time-reversal symmetry in a triplet superconductor Josephson junction is shown to cause a magnetic instability of the tunneling barrier. Using a Ginzburg-Landau analysis of the free energy, we predict that this novel functional behavior reflects the formation of an exotic Josephson state, distinguished by the existence of fractional flux quanta at the barrier. The crucial role o...
متن کاملOn Edge States in Superconductor with Time Inversion Symmetry Breaking
Superconducting states with different internal topology are discussed for the layered high-T c materials. If the time inversion symmetry is broken, the superconductivity is determined not only by the symmetry of the superconducting state, but also by the topology of the ground state. The latter is determined the integer-valued momentum-space topological invariant N. The current carrying boundar...
