| Electronic properties of 6-ZSiNR in the ground state. (a) Spatial spin density distribution. The isovalue is 0.006 a.u. (b) Spin-resolved band structures under E ext= 0, 0.1, and 0.25 V/Å, respectively. Inset: the band structure with E ext = 0.25 V/Å in the range of |E| < 0.1 eV and 0.7 π / a ≤ k ≤ π / a (the horizontal line is E f. The valence top or E f is set to zero. (c) The α -spin and β -spin orbitals of the conduction and valence bands, shown as the square of the absolute value of the wavefunction summed over all k -points. The isovalue is 0.275 a.u. The yellow arrow represents the energy shift direction of the spin states under a transverse electrical field. Blue and red denote α -spin and β -spin, respectively.
