- Abstract (EN)
- Angeli and MacDonald reported a superlattice imposed Dirac band in twisted bilayer molybdenum disulphide tBL MoS2 for small twist angles towards the parallel stacking. Using a hierarchical set of theoretical methods we show that the superlattices differ for twist angles with respect to metastable zero degree and lowest energy sixty degree configurations. When approaching parallel stacking identical domains with opposite spatial orientation emerge. They form a honeycomb superlattice yielding Dirac bands and a lateral spin texture distribution with opposite spin occupied K and K prime valleys. Small twist angles towards the sixty degree configuration generate stacking domains of different relative energies and therefore different spatial extensions. This imposes a symmetry break in the moire cell which opens a gap between the two top valence bands which become flat already for relatively small moire cells. The superlattices impose electronic superstructures resembling graphene and hexagonal boron nitride into the trivial semiconductor MoS2.
