We calculate nonlinear I–V characteristics in the system comprising a tunnel junction and a rectangle barrier to study the quantum interference effect using the lattice Green's function method based on Keldysh's theory. To investigate the feature of oscillatory behaviors of the total current in the presence of a bias voltage and magnetic field, we calculate the spatial distribution of a local current. Discussions are presented about an interpretation of the oscillation in terms of a periodic change of a local level and the interference of the wave function.
