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 ...

By subjecting graphite to extreme pressure and heat, researchers synthesized a rare hexagonal diamond, also known as lonsdaleite—a crystal structure that has long been theorized to be stronger ...

POSTECH and University of Montpellier researchers demonstrate wafer-scale AA-stacked hexagonal boron nitride (hBN) growth.

Zinc sulphide exists with two different crystal structures, the cubic zinc blend (top diagram) and the hexagonal Wurtzite (lower diagram). In the zinc blend structure the sulphur ions form an fcc ...

and the University of Montpellier have successfully synthesized wafer-scale hexagonal boron nitride (hBN) exhibiting an AA-stacking configuration, a crystal structure previously considered ...
