Abstract
Silicene nanoribbons (SNRs) will be doped with Ag atoms, silver atoms will be substituted at several positions in the structure of SNRs to create doped configurations. An external electric field of 0.1 V/Å will be applied to the doped systems. The theory used in this study is density functional theory (DFT). The doping profiles are optimized and they are all stable in the external electric field. The formation energies of the doped configurations will be calculated, the structure of energy bands and state densities of the systems will be plotted, investigated, and discussed. The study shows that the top configuration is a semi-metal, while the meta configuration is a semiconductor. Depending on the application, the system can use a semi-metal or a semiconductor, which creates a wide range of applications in electronic technology.
