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

Finally, the homogenisation of a semi-discrete elastic string structure, consisting of repeated hexagonal cells, is shown to coincide very closely with its discrete lattice counterpart.

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 ...

(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, ...

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 ...
