In this work, electrical and spin properties of armchair silicene nanoribbon (ASiNR) in the presence of charged impurity are studied. The non-equilibrium Green's function along with multi-orbital tight-binding is applied to obtain the transmission probability. Different types of spin transmission probability in the ASiNR on a substrate are investigated. The charged impurities are located in the underlying substrate. Spin-flip along the channel is calculated by using the spin transmission probability. The spin diffusion length in ASiNR for differently charged impurities is obtained and compared with the mean free path.
