Abstract:
In this paper, armchair bilayer graphene nanoribbon (BGNR) field effect transistor (FET) with adatom is investigated. Simulations are performed using non-equilibrium Green's function formalism. The obtained results show adding carbon atom to nano-structure of bilayer GNR increases the band gap energy but it does not change the off current. The current – voltage characteristic of BGNR FET with adatom is investigated and compared with no adatom case. The results show that adding atom will not change the on to off current ratio. Changing the position of adatom will not change the results.
