摘要：
The geometrical structures, electronic and transport properties of the folded zigzag graphene nanoribbon were investigated by using nonequilibrium Green's functions and the density-functional theory. It was found that the electronic and transport properties are determined by the folding degree of the zigzag graphene nanoribbon. The I-V curve is nearly linear for the large folding degree. The negative differential conductance in the zigzag graphene nanoribbon disappears with the large folding degree, and this is valuable for the rational design of the graphene-based electronic devices.
