Spatial Selected Spin Filtering Effect in Z-Shaped MoS2 Nanoribbon

Due to the gapless between any two successive subbands with the same spin, the spin polarization in uniform MoS2 zigzag nanoribbon (MoS2-ZR) is weak. Here, through configuring Z-shaped structure, we realize 100% spin polarization in MoS<sub...
