Using first-principles density functional theory and non-equilibrium Green’s function method, we investigated the electronic transport properties of C_20F_20 molecule. The calculation shows that the zero bias equilibrium conductance of C_20F_20 molecule is 0.385 G0. The I-V curve presents good linear characteristic. Under finite bias voltage the molecule displays stable conductance characteristic, and could be made as one steadying resistance molecular device.
