title: Influence of silver doping on electron transport in thin films of PbSe nanocrystals.
abstract: Field-effect transistors are fabricated from thin films of Ag-doped PbSe nanocrystals to analyze the influence of electronically active impurities on electrical transport in this important material for nanocrystal applications. Data is collected as a function of nanocrystal size, dopant concentration, and temperature. Changes in the Fermi level and transport parameters indicate that Ag is acting as a p-type dopant (acceptor).
