Query: Spin and charge thermopower of resonant tunneling diodes   We investigate thermoelectric effects in quantum well systems. Using the
scattering approach for coherent conductors, we calculate the thermocurrent and
thermopower both in the spin-degenerate case and in the presence of giant
Zeeman splitting due to magnetic interactions in the quantum well. We find that
the thermoelectric current at linear response is maximal when the well level is
aligned with the Fermi energy and is robust against thermal variations.
Furthermore, our results show a spin voltage generation in response to the
applied thermal bias, giving rise to large spin Seebeck effects tunable with
external magnetic fields, quantum well tailoring and background temperature.
