Visualizing defect dynamics by assembling the colloidal graphene lattice

Abstract: Graphene has been under intense scientific interest because of its remarkable optical, mechanical and electronic properties. Its honeycomb structure makes it an archetypical two-dimensional material exhibiting a photonic and phononic band gap with topologically protected states. Here, we assemble colloidal graphene, the analogue of atomic graphene using pseudo-trivalent patchy particles, allowing particle-scale insight into crystal growth and defect dynamics. We directly observe the formation and healing of co… Show more

“…[45] Moreover, trivalent colloidal particles assembled into graphenelike lattices, which even displayed defect rearrangement and self-healing abilities (Figure 4b). [46] In addition to patchy particles, metal-organic framework (MOF) materials are a novel type of building block with diverse polyhedral shapes, facilitating the formation of various lattices. [50] On the templateless assembly side, PMMA microspheres were successfully assembled in organic solvent with matched refractive index and density under an external electric field, which resulted in various lattice structures, including the non-close packed body-centered-cubic lattice.…”
