Thermoelectric properties of a single quantum dot in mixed-valence regime

We study thermoelectric effects in correlated quantum dot coupled to ferromagnetic electrodes by calculating thermal conductance κ, thermopower S and Figure of merit ZT in the mixed-valence regime as function of on-dot energy level and temperature. The system is represented by the Anderson model and the results agree well with those recently experimental measured for a quantum dot coupled to two leads.

► The thermoelectric effects in correlated quantum dot by calculating in the mixed-valence regime. ► The κ, S and ZT as function of on-dot energy and T were calculated by the nonequilibrium Green’s. ► The results of the thermoelectric effects agree well with those recently experimental measured.
