Abstract: | The reconstructed structure of Cu (100) surface induced by
atomic N adsorption is studied by using scanning tunneling
microscopy (STM). The 2D structure of copper boundary between
neighbouring N covered islands is found to be sensitive to the
growth conditions, e.g. N+ bombardment time and annealing
temperature. The copper boundary experiences a transition from
nano-scale stripe to nano-particle when the substrate is
continuously annealed at 623~K for a longer time. A well-defined
copper-stripe network can be achieved by precisely controlling the
growth conditions, which highlights the possibility of producing new
templates for nanofabrication. |
