High-chirality blue-phase lattices are unstable: A theory for the formation of blue phase III.

摘要: It is generally thought that the cholesteric liquid-crystal blue phases (BP), which are found near transition to isotropic liquid phase, particularly favored by high chiralities. shown here, contrary, lattice structures of BP I and II unstable in limit short pitch, this instability leads, turn, a mechanism, agrees with available experimental evidence, for formation III, seemingly amorphous phase
