Dimers (IMAGE) Georgia Institute of Technology Caption A model of the niobium nanowire with the electrical leads on the outside and the two dimers in the center. At left, the dimer is in the center of the leads, giving it high electrical conductivity. At right, the dimer is not centered, giving it lower conductivity. For the full image click the link below.
