Deskripsi
Due to the gapless between any two successive subbands with the same spin, the spin polarization in uniform MoS<sub>2</sub> zigzag nanoribbon (MoS<sub>2</sub>-ZR) is weak. Here, through configuring Z-shaped structure, we realize 100% spin polarization in MoS<sub>2</sub>-ZR with only exchange field. The filtered spin electrons transmit along a specified edge of the device. This phenomenon is the result of the combined effect of the localized edge states and structure induced inversion of the Mo-edge and S-edge. In our calculation the fully spin polarization appears in several energy regions, so this Z-shaped MoS<sub>2</sub>-ZRs can be used in making spintronic devices.
