Physicists discover 'super crystals' in a semiconductor

In this schematic drawing of a super-crystalline phase, the blue balls represent the periodically arranged organic molecules and the dashed lines represent a periodic superlattice of soliton walls. The superlattice D is from hundreds to thousands times larger than the period of the crystal, d. The soliton walls serve as traps for electrons, represented by red balls. The soliton wall superlattice and electron standing waves, localized on the walls, give super crystals their unique conducting properties. Credit: Courtesy of Andrei Lebed and Si Wu
