Heat generation by spin-polarized current in a quantum dot connected to spin battery and ferromagnetic lead |
Schematic plot of a quantum dot coupled to the left spin battery and the right ferromagnetic lead. The spin battery induces spin-dependent chemical potentials in the left lead. The heat results from the electron–phonon interaction, through which the energy associated with the spin-polarized current passing through the dot is transferred to the phonon bath in the form of heat. |
