Theoretical Study on Effect of Defective Connection to Reservoirs in an Atomic-Scale Conductor

Figure 2

Current-voltage characteristics calculated for size of the conductor and and effective mass . The right inset shows schematic structure at the cathode-conductor interface where cross denotes the defect. The curves labeled “1,” “3,” and “5” denote current for a defect at the 1st, 3rd, and 5th rows in the interface, respectively. The left inset shows the resistance as a function of the defect position.
