Abstract:
A process to prepare stoichiometric-nanostructured materials comprising:generating a plasma; forming an â€œactive volumeâ€  through introduction of an oxidizing gas into the plasma, before the plasma is expanded into a field-free zone, either (1) in a region in close proximity to a zone of charge carrier generation, or (2) in a region of current conduction between field generating elements, including the surface of the field generation elements; and transferring energy from the plasma to a precursor material or materials and forming in the â€œactive volumeâ€  at least one of stoichiometric-nanostructured materials and a vapor that may be condensed to form a stoichiometric-nanostructured material.
