We have been working on applications of gold-nanoparticle (GNP) assemblies as physical reservoirs. Last year, we reported the characteristics at liquid helium temperature of a six-terminal device fabricated by a multi-step immersion method using 30 nm diameter GNP colloids. In this study, we increased the number of terminals from 6 to 12. We also mixed 15 nm diameter GNP colloids to increase the charging energy of the GNPs within the assembly. We report the device characteristics at liquid nitrogen temperature.
