Controlling the formation of gold nanoparticle domains onto inorganic substrates

Abstract The ability to control the spatial arrangement of molecular nanocrystals is of fundamental importance for the fabrication of nanoscale devices. In this work, we report on experimental procedures to control the formation of 50 nm, organically capped, gold nanoparticles by tuning the deposition conditions. We found the parameters which lead to the formation of different domain structures, from three-dimensional aggregates to two-dimensional structures, to even isolated particles.
