This array formed a unique broken hexagonal structure due to the competition between hexagonal lattice symmetry and uniaxial ...

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 = ...

which is composed of a single flat layer of carbon atoms arranged in a repeating hexagonal lattice. Now, researchers from the ...

Scientists describe graphene as a nanomaterial that is effectively two-dimensional, because the hexagonal lattice structure that makes it up is only one atom thick. About 200 time stronger than ...

(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, ...
