Quasiperiodic van der Waals heterostructures of graphene and hexagonal boron nitride

Advancement toward opening a bandgap at the Dirac point induced by symmetry breaking paved way to realize 2D heterostructures with graphene and hexagonal boron nitride (h-BN). An alternate arrangement of h-BN layers in 3D stacking can tune bandgaps these composites depending on position B N atoms respect C graphene. Herein, unique possibility arranging atomic quasiperiodic Fibonacci sequence study possibilities controlling electronic properties is explored. Density functional theory calculations combined van der Waals corrections reveal that are more stable than normal periodic monolayers h-BN. Moreover, for certain arrangements layers, sizeable be obtained.
