Symmetry-Dependent Spin Transport Properties and Spin-Filter Effects in Zigzag-Edged Germanene Nanoribbons

Figure 2

Spin-dependent - curves and transmission spectra as a function of electron energy and bias . (a, b) Spin-up state of 5-ZGeNR; (c, d) Spin-down state of 5-ZGeNR; (e, f) Spin-up state of 6-ZGeNR; (g, h) Spin-down state of 6-ZGeNR. The region between the solid lines is referred to as bias window, which sets boundaries for transmission that contributes to the current at a given bias voltage. The Fermi level is set to zero.
