Abstract

In this paper, the electronic and transport properties of three groups of armchair Silicene nanoribbons were investigated in the presence of a vertical magnetic field. The Silicene nanoribbons were modeled with N=5-7 silicon atoms in width, each having different band gaps. Vertical magnetic field with strengths of h=0.1 eV, 0.2 eV, and 0.3 eV were applied to the nanoribbons. By applying a vertical magnetic field, changes were observed in the electronic arrangement of the nanoribbons. As a result, the electronic and transport properties of nanoribbons such as emission spectrum, band structure, and current-voltage (I-V) characteristics were changed. The results indicated that applying a vertical magnetic field to the armchair silicene nanoribbons subjected to electric potential difference enhances the current. To extract the electronic and transport properties of the nanoribbons, a tight-binding model coupled with the non-equilibrium Green’s function formalism was employed.
