“…For sufficiently low temperatures, the sequence of structures for increasing volume fraction of the particles is: disordered (D phase), cluster crystal with a cubic symmetry (C phase), hexagonally ordered cylindrical clusters (H phase), parallel layers (L phase), hexagonally ordered cylindrical voids (IH phase), cubic crystal of spherical voids (IC phase), and again the disordered phase. In addition, a gyroid G phase is stable between the H and L phases, and the IG phase is stable between the L and IH phases for some temperature range [1,3,13,20]. Theories of meanfield nature predict the above sequence of phases for the whole range of T < T L , where above T L only the disordered phase (no periodic structure) is stable for the whole range of the volume fractions [1,3,11].…”
