摘要：

We compute phase diagrams for diblock copolymers in the strong-segregation regime as a function of volume fraction phi. We include the ordered bicontinuous double-diamond (OBDD) phase, which is found to be stable between cylinders and lamellae, consistent with experiment, for phi (or 1 - phi) between 0.19 and 0.27. Our phase diagram relies on taking into account the hexagonal shape of the unit cell for the cylindrical phase, and the unique geometry of the OBDD phase.
