The formation of supported monodisperse Au nanoparticles by UV/ozone oxidation process
Abstract
The influence of surface preparation of GaAs (100)- and (111)B-oriented substrates on the self-assembly of Au nanoparticles has been investigated. It has been shown that an UV/ozone surface oxidation process, applied prior to the deposition of a thin Au film, enables the formation of well-distributed Au particles that are very uniform in size. Particles of 4.5±1.4nm diameter have been obtained by the appropriate heat treatment of a 1-nm-thick …
