(a) Molecular organization in the twist cell (top view) and the angular offset
φ, which characterizes the angle at which the ribbon is cut. The orientation
of the molecules at midplane is shown with a double-headed arrow. The cutting direction, which is also the long axis of the ribbon, is represented by a dotted line.
The elongated rods represent molecules (left) and the twist-nematic molecular orientation through the thickness of the
film (side view) (right). (b) Schematic
