Geometry of the nanostrips studied in this work. All nanostrips consist of two layers with opposite chirality (light and dark grey), the interface is located at \(z=0\,{\textrm{nm}}\). Length l and width w are adjusted as required. In a later part of this work we also study the effect of notches with width \(n_x\) and depth \(n_y\) in the strip. They extend throughout the whole sample thickness, as shown here. The colour and the streamlines on the top surface show the current density and direction in the nanostrip with a notch.
