研究目的
Investigating the effects of B and/or N doping on the electronic band structure of bilayer graphene, with a focus on the modifications due to the presence of B-N pairs.
研究成果
Introduction of B-N pairs into bilayer graphene can be used to tune the size of the band gap without critically affecting the band dispersions, offering a method for band gap engineering in graphene-based electronics.
研究不足
The study is limited to theoretical calculations and does not include experimental validation. The effects of higher dopant concentrations or different doping configurations are not explored.
