摘要: The aim was to study the electronic transport of molecular devices constructed by salicylidene aniline molecule and graphene electrodes using density functional theory non-equilibrium Green’s function. calculated results demonstrate a switching behavior in two photoisomerizations. In addition, modification –OH on edge nanoribbons induces variety frontier orbitals increase current, but decrease ratio. F improves We explain negative differential resistance effect found device transmission spectra evolution local states at bias. indicate that different modifications influence transport. This method can improve application future circuits.
