摘要: Abstract Recent calculations (Mahmoud and Lugli, 2013, [21] ) of gold leads sandwiching carbon chains which are separated by diphenyl–dimethyl demonstrated that the negative differential resistance (NDR) effect appears only for “odd” numbers atoms. In this paper, according to a first-principles study based on non-equilibrium Green's function combining density functional theory, we find NDR both “even” atoms when doped nitrogen atom. Our remove restriction “odd/even” effect, may promise potential applications in nano-scale or molecular devices future.
