Properties of silicene nanoribbons when doped with two indium atoms in an external electric field Available to Purchase

Silicene is a two-dimensional material that has been studied a lot in recent years, silicene nanoribbons are one-dimensional materials made from silicene. The edges of silicene nanoribbons are modified with hydrogen. This work studies doping two In atoms into each unit cell of silicene nanoribbons, and the system is placed in an external electric field. The method here is to use density functional theory (DFT). The formation energies, energy band structures, and state densities of the configurations will be calculated, discussed, and plotted. There are three two-atom doped configurations studied here as meta-configuration, ortho-configuration, and para-configuration. The external electric field with the presence of indium changes the band gap of the system, leading to a change in its electronic properties.
