(Color online) Spin-dependent electronic thermal conductance ${\kappa }_{el,\sigma }^V$ and ${\kappa }_{el,\sigma }^T$ , charge and spin figure of merit Z _C T and Z _S T as function of the chemical potential μ under several different values of λ at room temperature (T = 300 K). Thick black solid (red dashed) lines in [an(n = 1,..., 4)] denotes spin-up electronic thermal conductance ${\kappa }_{el,\uparrow }^T$. Thin black solid (red dashed) lines in [an(n = 1,..., 4)] denotes spin-down electronic thermal conductance ${\kappa }_{el,\downarrow }^T$. The black solid lines in [bn(n = 1,..., 4)] represent the charge FOM Z _C T, and the red dashed lines in [bn(n = 1,..., 4)] represent the spin FOM.
