Thanks to the crystal structure of diamonds, with carbon atoms arranged into a lattice-like structure, diamond is top of the ...

Hexagonal close packing is one of two crystal structures that derive from stacking close-packed-planes of hard sphere atoms. In the HCP structure only two stacking ...

The hexagonal wurtzite structure has the sulphur ions in an hcp array and one-half of the tetrahedral sites in this structure are occupied by zinc ions. The crystal has a basal lattice parameter, a = ...

(Image: Empa) Graphene nanoribbons are narrow strips of graphene, a single layer of carbon atoms arranged in a hexagonal lattice. GNRs can have different edge structures, such as armchair or zigzag, ...
