Extended Data Fig. 1: Crystal structure and Brillouin zone of hBN.
From: Light-wave-controlled Haldane model in monolayer hexagonal boron nitride
a, Crystal lattice of monolayer hBN up to next-nearest neighbours. Each atom Anm is labelled by its sub-lattice (A or B) and by its lattice vector \({{\boldsymbol{R}}}_{{nm}}=n{{\boldsymbol{a}}}_{1}+m{{\boldsymbol{a}}}_{2}\). In Eq. 2, the angle α between two atoms is defined according to the inset in the top left. b, First Brillouin zone of monolayer hBN and its high-symmetry points.
