Effect of point defects in armchair graphene nanoribbons for biosensing of Methanethiol biomarkers: A DFT Study
2021 IEEE 21st International Conference on Nanotechnology (NANO)(2021)
摘要
In this study, we probe the surface engineered (vacancy and Stone Wales defective) hydrogen passivated armchair graphene nanoribbon with a width of 7 atoms as a biosensing material to detect methanethiol biomarkers. Induction of defects results in the decrement of the bandgap by the formation of the trapping states. After geometry optimisation, it is found that only vacancy induced armchair graphe...
