Full TextAbstract
Spin dependent transport of transition metals doped Zigzag Silicene Nano-Ribbons (ZSiNR) are investigated through the Density Functional Theory (DFT) and Non-Equilibrium Green's Functions (NEGF) formalism. The edge dangling bonds are passivated with hydrogen atoms. The DOS and Transmission functions are calculated and the resulting I-V curves show a behavior characteristics of spin polarized currents. These facts results in Negative Differential Resistance (NDR) and a reasonable Spin-Filtering Effect (SFE) in doped ZSiNRs compared to the pristine ZSiNR which shows the applicability of the considered structures in spintronic devices.
