ABSTRACT
yere, we report a hydrothermal chemical-vapor deposition process, which produces self-assembled patterns of iron oxide nanoparticles. By exposing a planar silica substrate to a prevaporized mixture of water, ferrocene [Fe(C[sub 5]H[sub 5])[sub 2]] and xylene (C[sub 8]H[sub 10]), at temperatures of ∼1000°C, Fe[sub 2]O[sub 3] nanoparticles are deposited on the substrate surface, in regular circular patterns. The particle sizes are less than 100 nm, and are organized into submicron-size patterns. The same process without water produces arrays of carbon nanotubes catalyzed by iron nanoparticles that are formed by the decomposition of ferrocene molecules. © 2001 American Institute of Physics.
