In solving the Schr "odinger equation to simulate a nanoscale circuit, we\nnote that the mean free path for electrons in some metals is as large as 48 nm.\nThus, the wavefunction may propagate coherently through wires corresponding to\nthe lines that show the potential outside of the tunneling junction. A voltage\nsource may be modeled as a jump in the potential. Similarly, the potential\nacross a resistor may be modeled as a sharp drop or a downward sloping line to\nshow a decrease in the potential. Then the resistance may be determined by\ndividing this voltage drop by the product of the calculated current density and\nthe effective cross-sectional area.\n
