Figure 2From: Statistical and electrical properties of the conduction electrons of a metal nanosphere in the region of metal-insulator transitionFermi energies and variances of the occupation numbers of electronic states of single Ag or Au spheres. (a) Fermi energy as a function of the number N of conduction electrons. (b) Sums of the variances Δ normalized to the bulk metal value Δb in canonical ensembles (points) and grand canonical ones (crosses). The grid lines are the same as in Figure 1.Back to article page
