Depositing gold on the insulating AlN(0001) surface results in the formation of metallic islands with a thickness of one atomic layer and lateral dimensions in the 100nm range. This structure is quite unusual for a metal-on-insulator system. High-resolution NC AFM images coupled to DFT calculations show that some Au atoms react on specific sites of the surface. These islands are good candidates to be used as nano-electrodes to contact a single nano-object such as a molecule.
