Engineering 2D Materials from Single-Layer NbS₂.

ABSTRACT: Starting from a single layer of NbS₂ grown on graphene by molecular beam epitaxy, the single unit cell thick 2D materials Nb_5/3S₃-2D and Nb₂S₃-2D are created using two different pathways. Either annealing under sulfur-deficient conditions at progressively higher temperatures or deposition of increasing amounts of Nb at elevated temperature result in phase-pure Nb_5/3S₃-2D followed by Nb₂S₃-2D. The materials are characterized by scanning tunneling microscopy, scanning tunneling spectroscopy, and X-ray photoemission spectroscopy. The experimental assessment combined with systematic density functional theory calculations reveals their structure. The 2D materials are covalently bound without any v
