SUMMARY

The discussion centers on the impact of substituting one Carbon atom in a graphene layer with Boron and another with Nitrogen, specifically regarding the potential for creating an open band gap. It is established that this substitution can indeed lead to an open band gap due to the breaking of space inversion symmetry. The Haldane Model is referenced as a significant theoretical framework to support this hypothesis. Literature on this topic is sought to further explore the implications of these substitutions.

PREREQUISITES
  • Understanding of graphene structure and properties
  • Familiarity with band gap concepts in semiconductors
  • Knowledge of the Haldane Model in condensed matter physics
  • Basic principles of doping in materials science
NEXT STEPS
  • Research the Haldane Model and its applications in graphene
  • Explore literature on the effects of Boron and Nitrogen doping in graphene
  • Investigate experimental methods for measuring band gaps in 2D materials
  • Study the implications of space inversion symmetry in semiconductor physics
USEFUL FOR

Materials scientists, condensed matter physicists, and researchers focused on graphene and semiconductor applications will benefit from this discussion.

I had a task from my supervisor, graphene layer has 2 Carbon atoms per unit cell. What will happen if the atoms are replaced by one atom Boron and one atom Nitrogen? Will we found an open band gap?
Would you please inform me any literature concerning it?

I guess it will open a gap because it break the space inverse symmetry. You can get help from the famous Haldane Model.
 
Thank you very much guyingfei. I'll try it
