Two Al-doped silicene nanoribbons will be investigated in this work. The constant electric field acting on the doped system is 0.4V/Å. By changing the doping site, three doped structures will be studied. The configuration and electronic characteristics of the doped system will be studied based on density functional theory (DFT). The meta-configuration shows a more stable advantage in the electric field than the other configurations due to its minimal formation energy. The partial and total orbitals will also be investigated for their contribution to the formation of bands. This research points towards future applications for electronic devices at the nanometer scale.
