Many envisioned applications of semiconductor nanocrystals (NCs), such as thermoelectric generators and transparent conductors, require metallic (nonactivated) charge transport across an NC network. Although encouraging signs of metallic or near-metallic transport have been reported, a thorough demonstration of nonzero conductivity, , in the 0 K limit has been elusive. Here, we examine the temperature dependence of of ZnO NC networks. Attaining both higher and lower temperature than in previous... Science Magazine · 4 weeks
