โœฆ Synopsis


By applying non-equilibrium Green's function (NEGF) formalism combined with first-principles density functional theory (DFT), we have investigated the electronic transport properties of the anthraquinonebased molecular switch. The molecule that comprises the switch can be converted between the hydroquinone (HQ) and anthraquinone (AQ) forms via redox reactions. The transmission spectra of these two forms are remarkably distinctive. Our results show that the current through the HQ form is significantly larger than that through the AQ form, which suggests that this system has attractive potential application in future molecular switch technology.

We have studied the switching characteristics of an optical molecular switch based on the phenoxynaphthacenequinone (PNQN) molecule with two armchair single-walled carbon nanotube (SWCNT) electrodes using the first-principles density functional-based non-equilibrium Green's function (DFT-NEGF) metho
