Orientation of BPII(111) on different surfaces. (A) The BPII(111) is the preferred orientation that a BPII adopts when it is confined by uniform homeotropic surfaces. (B) Previous results have shown, however, that confinement, combined with assembly on a patterned surface, induces a hexagonal blue phase (HBP) in the proximity of the treated surface. The BP is frustrated by the patterned surface, and it has to change its defect configuration near the surface to accommodate the confinement.
