Enhanced spin-dependent thermopower in a double-quantum-dot sandwiched between two-dimensional electron gases

Chi Feng¹, Fu Zhen-Guo^{2, †}, Liu Liming¹, Zhang Ping^{2, ‡}

Spin-dependent thermopower S σ in (a) and (c), and charge and spin thermopowers in (b) and (d) as functions of the chemical potential μ at temperature T = 0.015 Γ / k B . In (a) and (b), Δ = 0.05 Γ , E z = 0.025 Γ , and in (c) and (d), Δ = E z = 0.05 Γ . The other parameters are the same as those in Fig. 2.
