    • Equation (3) holds provided there is not direct coupling between the electrodes. In the local representation used in this paper this is practically always true.

    • On the grid this contribution is not singular, but is still unphysical and has to be subtracted.

    • Equation (21) expresses the fact that removing the surface S from the semi-infinite reservoir R leaves a system identical to the original R.

    • The choice of relatively small values for the barrier height and the work function saves numerical work by making it possible to use in this numerical example a relatively coarse grid.

    • note
    • Obviously a better result would be obtained by taking a smaller Φ interval that contains the desired resonance state, i.e. by taking the numerical derivative dI/dΦ at resonance. Note that using the Landauer formular for the conduction instead of numerically evaluation this derivative is valid only in the linear conduction regime. In the general case it misses the dependence of the transmission probability on the voltage.
