Article Synopsis
- Tailoring band gaps in semiconductors is crucial for creating innovative devices, typically done through energetic ion implantation, but 2D materials offer new methods via their sensitivity to surrounding dielectrics.
- Researchers have demonstrated significant changes in the exciton binding energy of monolayer WSe by varying the dielectric constant, achieving a reduction of up to 300 meV with increased dielectric values.
- The findings correlate well with theoretical predictions from a Mott-Wannier model, and the study suggests that manipulating the dielectric environment could lead to exciton metamaterials through potential-well arrays in 2D materials.
