In the present work, the effect of a central electrical impurity (dipole) on quantum conductance in simple cubic nano-wires (SCNW) has been investigated in the tight-binding (TB) approach and assuming nearest-neighbor interaction by Green?s function (GF) method. We illustrate that in the presence of electrical impurity (external potential), the number of channels and energy band of nano-wire decrease. The variation of the energy band and the number of channels depend on the position and amount of the electrical charge (dipole moment) in the SCNW
