Resistance measurements on a single nanoparticle and nanoparticle ensembles — •Ivan S. Titov, Marina Spasova, and Michael Farle — Fakultät für Physik and CeNIDE, Universität Duisburg-Essen, 47048 Duisburg, Germany

In this work the resistance of 18 nm iron oxide nanocubes was measured using Scanning Tunneling Microscope mounted inside of Transmission Electron Microscope (TEM-STM technique). Chain-like structures consisting of the arbitrary numbers of the cubes were built using tungsten STM tips. The process of the chain formation was visualized in TEM. Voltage-current curves for a single nanocube and nanocube chains were recorded in a contact STM mode using gold and tungsten tips. Correlation of electrical properties with the structure and the chain morphology as well as influence of contact resistance and deformation of the samples on measured resistance values are discussed. The work is supported by DFG/SFB 445.
