Temperature-modulated scanning tunneling spectroscopy of gold nanoparticle dropcast films

Abstract

The electronic conductivity of a gold nanoparticle dropcast film was examined by temperature-modulated scanning tunneling spectroscopy (STS). The low-conductance Coulomb blockade was found to shrink with increasing temperature, which at ambient temperature (ca. 290 K) diminished completely. Concomitantly, the potential spacing between adjacent peaks… (More)
