Figure 1.

A sketch of the physical system to be studied. The system can be regarded as a 3D superlattice with one thin film (thickness a) and one stripe-shaped layer (thickness c along the z direction and width b along the x direction) stacked alternatively; the spacing between two adjacent stripes is d. The transport direction is along the x axis.
