Table 1

Atomic dopant wires of different width. L and w denote the lithographic length and width of each wire studied. Ael and del are the effective electronic cross section and diameter of the wires as determined by atomistic calculations. Resistivities, ρW, were extracted from the wire resistance RW using Ael. Measured wire resistances are compared to theoretically predictions Rcalc based on the tight-binding calculations.
