Owing to its hexagonal lattice structure with a diatomic unit ... at energies ±ℏv F |G|/2 given by the reciprocal superlattice vectors G(refs 2, 3), where v F is the Fermi velocity.

Researchers have previously pursued harder diamonds with hexagonal rather than cubic lattices ... However, past attempts to make hexagon-lattice synthetic diamonds have resulted in diamonds ...

By finely varying a magnetic field applied perpendicularly to the thin plate, the researchers were able to induce a transformation between the square lattice of merons-antimerons and a hexagonal ...
