Figure 9.28. Coulomb staircase structure on plots of current I and derivative d//dV versus the
bias voltage V of a granular lead film Josephson junction. It is clear that the first-derivative
response provides much better resolution. [From K. A. McGreer, J.-C. Wan, N. Anand, and

by the differential plot of dZ/dY versus Y than they are on the initial Z-Yplot. This
superconductor Coulomb staircase is similar to the much better resolved one
presented in Fig. 9.18 for single-electron tunneling in quantum dots.
