Orientation-Dependent Performance Analysis of Benzene/Graphene-Based Single-Electron Transistors

  • Published:
Journal of Electronic Materials Aims and scope Submit manuscript

The present paper discusses charge stability and conductance analyses of benzene- and zigzag graphene fragment-based single-electron transistors (SETs) operating in the Coulomb blockade regime. Graphene and benzene are modeled using density functional theory-based ab initio analyses, treating the interaction between graphene/benzene and the SET environment self-consistently. The devices consist of an oriented graphene/benzene island coupled with source and drain electrodes. The charging energy as a function of the external gate potential has been analyzed to verify the dependence of the charge stability and conductance of the oriented SETs on the source/drain bias and gate potential. Comparative analysis of these models shows that the SET with vertically oriented graphene is more stable and has better conductance in comparison with the benzene-based SET.
