In this paper, we study the electronic conductance of a nanoribbon with square lattice by using Green’s function theory within the tight-binding approach. For this purpose, we separate the conductance modes in the ideal parts by using a suitable unitary transformation in order to obtain the analytic formula for the corresponding self-energies. Then, we present a fast computer algorithm based on the Fisher-Lee formula for the calculation of the system conductance. The results show that the distribution of electrical impurities with different on-site energies leads to the different values of the system electronic conductance and it is generally decreasing.
