Electronic properties of NBS₂ single layers Li, Zhanming


A theory of optically and magnetically anisotropic NbS₂ platelets suspended in water is developed, and a two dimensional tight-binding model is used to describe the magnetic and optical properties of single layer NbS₂ and NbSe₂. For the first time both polarization and transition matrix effects are included in calculating the intensities of absorption of the transition metal dichalcogenides. The results are in qualitative agreement with experiments and can be interpreted in terms of the two dimensional(2D) nature of the band structure.
