    • Electro-absorption of silicene and bilayer graphene quantum dots 

      Abdelsalam, H.; Talaat, M.H.; Lukyanchuk, I.; Portnoi, M.E.; Saroka, Vasil (Journal article; Peer reviewed, 2016)
      We study numerically the optical properties of low-buckled silicene and AB-stacked bilayer graphene quantum dots subjected to an external electric field, which is normal to their surface. Within the tight-binding model, ...

    • Electro-optical properties of phoshorene quantum dots 

      Saroka, Vasil; Lukyanchuk, I.; Portnoi, M.E.; Abdelsalam, H. (Journal article; Peer reviewed, 2017)
      We study electronic and optical properties of single layer phosphorene quantum dots with various shapes, sizes, and edge types (including disordered edges) subjected to an external electric field normal to the structure ...

    • Multilayer phosphorene quantum dots in an electric field: Energy levels and optical absorption 

      Abdelsalam, H.; Saroka, Vasil; Lukyanchuk, I.; Portnoi, M.E. (Journal article; Peer reviewed, 2018)
      Triangular and hexagonal multilayer phosphorene quantum dots with armchair and zigzag terminations are investigated with the orthogonal tight-binding model. The effect of increasing the number of layers is revealed. The ...
