Gold nanoparticles serve as ultra-small electron dispensers and make possible the control of electric current with the accuracy of a single electron (Coulomb blockade). The challenge is to fabricate reproducible architectures where gold nanoparticles of diameters between 5 and 10 nm are deposited on top of a GOM molecular layer which plays the role of an insulating layer (tunnel barrier) and which is grafted on a silicon substrate. The experimental study is carried out in ultra-high vacuum with a STM (Scanning Tunnel Microscope).
