From: Electronically stabilized nanowire growth

Figure 4

Spatial variation of the differential conductivity at the Fermi level for an Ir nanowire with a length of 4.8 nm (a) and 9.6 nm (b). (c) Spatial variation of the differential conductivity at V=−0.275 V for the Ir nanowire from graph b. r=0 refers to one of the ends of the nanowire. The solid lines serve as a guide to the eye. STM images of the Ir nanowires are shown at the top of the graphs. The sample bias is −1 V and the tunnel current is 0.5 nA. These values were also used as set points for the I–V curves.
