Abstract In modern two-dimensional (2D) materials, such as graphene-based systems and atomically thin transition-metal dichalcogenides, the interplay of strong electronic correlations, tunable moiré superlattices, and nontrivial band topology has given rise to rich phase diagrams and collective phenomena. Among the novel phases that have been realized, electronic crystals—states of matter in which itinerant electrons spontaneously crystallize—play a particularly prominent role.
