Summary:A two-dimensional (2D) artificial lattice composed of metal nanoparticles was fabricated and its electrical characteristics were controlled. Each nanoparticle was a 3-nm-diameter gold core covered with thiolate ligands. The fabrication of the 2D artificial lattice was achieved by using the Langmuir-Blodgett method. The conductance of the lattice increases with decreasing length of the thiolate ligands. As well as by the chemical approach, the conductance can also be controlled by a physical approach such as applying an external pressure.
