The charge density distribution of the system was obtained by using the self-consistent field method. The charge density matrix of the system was analyzed according to the exciton theory, and the spectrum distribution of the surface plasmon polariton (SPP) was deduced. The matrix of current transport was constructed on the atomic orbital basis And then use the SPP spectral specification current transport matrix to obtain the expression of current transport polynomial expression.Then put forward the SPP influence the current transport and lead to the negative resistance of the physical image
