Minimal d-Band Model for Optical Properties of TMDC Monolayers
Analysis
This paper introduces a simplified model for calculating the optical properties of 2D transition metal dichalcogenides (TMDCs). By focusing on the d-orbitals, the authors create a computationally efficient method that accurately reproduces ab initio calculations. This approach is significant because it allows for the inclusion of complex effects like many-body interactions and spin-orbit coupling in a more manageable way, paving the way for more detailed and accurate simulations of these materials.
Key Takeaways
- •Develops a simplified d-band model for calculating optical properties of TMDC monolayers.
- •The model is computationally efficient and reproduces ab initio calculations.
- •Facilitates the inclusion of many-body effects and spin-orbit coupling.
- •Offers a pathway for more detailed and accurate simulations of TMDCs.
“The authors state that their approach 'reproduces well first principles calculations and could be the starting point for the inclusion of many-body effects and spin-orbit coupling (SOC) in TMDCs with only a few energy bands in a numerically inexpensive way.'”
