All-Inorganic Nanocrystal Arrays

摘要

In a bid to create conductive nanoscale devices using solution-phase chemical strategies, Talapin et al. have created 2D all-inorganic nanocrystal (NC) arrays by replacing the traditional (insulating) organic surface ligands of NCs created by solution-phase arrested-precipitation routes with inorganic clusters; subsequent self-assembly yields organized networks. Once annealed, electron transport between particles becomes facile, mediated by the conductive inorganic interfaces, thus enabling formation of, for example, semiconducting NC-based field-effect transistors.
