Figure 2From: Quantum interference effect in electron tunneling through a quantum-dot-ring spin valve Total current J , current spin polarization p and TMR each as a function of the bias voltage for different values of φ . t LR = 0 in Figs. (a) to (c) and t LR = 0.01 in Figs. (d) to (f). The other parameters are intradot energy level ε d = 0, temperature T = 0.01, and polarization of the leads P L = P R = 0.4.Back to article page
