Abstract:Delocalized–localized electron interactions are
central
to strongly correlated electron phenomena. Here, we study the Kondo
effect, a prototypical strongly correlated phenomena, in a tunable
fashion using gold nanostructures (nanoparticle, NP, and nanoshell,
NS) + molecule cross-linkers (butanedithiol, BDT). NP films exhibit
hallmark signatures of the Kondo effect, including (1) a log temperature
resistance upturn as temperature decreases in a metallic regime, and
(2) zero-bias conductance peaks (ZBCPs) that a… Show more
