Figure 2: Resistivity of an annealed nanocrystal film.

Resistivity of an annealed nanocrystal film, prepared using the same conditions as in Fig. 1c, as a function of time in a vacuum chamber during pump down (red). The pressure in the chamber as a function of time is the black points. The two curves were combined to give the inset, resistivity as a function of residual air pressure in the vacuum chamber.
