Query: Growth of Epitaxial Tungsten Nanorods   A simple vapour deposition technique was used to prepare WO3 one-dimensional
nanostructures.WO3 is sublimated at a relatively low temperature (550 1C) in
air at atmospheric pressure.The sublimated species are condensed on mica
substrate at 500 1C.Single crystalline nanorods are grown in epitaxy on the
mica surface with a growth axis along [0 1 0] directions and (0 0 1) plane
parallel to the substrate.A growth process is proposed in which the formation
of a onedimensional tetragonal tungsten bronze as precursor is the determining
factor.
