Indium-doped silicene nanoribbons in the presence of an external electric field

The study of silicene is a turning point in two-dimensional materials, like graphene and germanene, silicene is a promising material due to its remarkable structural properties. This work investigates silicene nanoribbons (SNRs), which are one-dimensional materials made from silicene with hydrogen-modified edges. The article studies doping indium elements into SNRs. Three doped configurations are focused on research: top configuration, valley configuration, and 100% configuration. Although an electric field with magnitude 0.35V/Angstrom is present, the doped configurations are not broken and stable. By using density functional theory (DFT), formation energy, energy band structure, density of states will be calculated and discussed.
