Figure 2

Energy-optimal simulated structure of cholesteric layer: top view, cross-cut at the top surface (a); side view, cross-cut perpendicular to the strip lines (b). Dashed black lines show cross-cut directions. The director vectors are colored in correspondence with their direction (x—blue, y—red, z—green). POM images of CLC layer taken in the crossed polarizers (c) and at angle \(40^\circ\) between polarizer and analyzer (d) when \(V=0\) V. The enlarged area with \(\hbox {U}^+\)-defect marked by the blue frame in Fig. 2d (e). The scheme of director distribution on the top substrate near \(\hbox {U}^+\)-defect (f).
