    In this paper, we study the effect of single Boron/Nitrogen impurity
    atom on electronic properties of a silicene nano flake. Our calculations are based
    on density functional theory by using Gaussian package. Here, one Si atom in
    silicene nano flake substitutes with a Boron/Nitrogen atom. The results show that
    substitution of one Si atom with single Boron/Nitrogen atom increases distance
    of impurity atom with its nearest neighbors and changes hexagonal structure of
    silicene nano flake. Doping silicene nano flake with a Boron impurity atom makes
    its structure curved and causes to create a miniband in energy gap, which
    increases conductance consequently while doping with a Nitrogen atom causes
    to produce two spin dependent midbands in energy gap which leads to creating a
    controllable spin dependent conductance with electron energy for silicene nano
    flake. Therefore, Nitrogen doped silicene nano flake is good material for design
    of nano electronic and spintronic devices.
