Resumo
© 2025This work presents the electronic and transport properties of bilayer borophene nanoribbons. In the first part, a four-orbital tight-binding model is derived by fitting the ab initio band structure. The transport properties of armchair and zigzag bilayer borophene nanoribbons are then analyzed, both with and without periodic boundary conditions. In both scenarios, the nodal line causes conductance to increase with width and exhibit oscillations in narrow nanoribbons. Additionally, plots of current and charge density reveal that edge states have a more pronounced impact in narrower nanoribbons. Finally, uniaxial tensile strain is introduced as a tool to engineer the number of available transport channels.
