Fabrication and modeling of a combined gold nanoparticle-carbon nanotube single electron transistor

In English Scanning probe manipulation has been used to electrically connect two carbon nanotubes to an individual 7 nm gold particle, resulting in a system with multiple tunnel junctions. Single-electron charging effects in the gold particle was found to dominate the electrical transport measurements at T=4.2 K, whereas charging effects in the two carbon nanotube leads appeared as a fine structure. A simulation of the electrical transport in the system has been carried out using SIMON*, which is a Monte Carlo based simulation program for single-electronics. Using this program we have been able to fit a model to the experimental data and to explain the electrical transport characteristics
