Temperature dependence on the charge transport behaviour of 3-D superlattice crystals of mercaptosuccinic acid-protected gold nanoparticles

Abstract

The electric charge transport behavior of a random assembly of three-dimensional superlattice crystals (having different core sizes) of mercaptosuccinic acid-protected gold nanoparticles showed a unique behavior of metallic-like nature at low temperatures and semiconductor nature at high temperatures in addition to a reversible transition feature in the hopping region. © 2009 the Owner Societies.
