Control and Modification of Nanostructured Materials by Electron Beam Irradiation

I have proposed a bottom-up technology utilising irradiation with active beams, such as electrons and ions, to achieve nanostructures size of 3–40 nm. This can be used nanotechnology that provides the desired structures, materials, phases at positions. Electron beam metastable θ-Al2O3, more than 1019 e/cm2s in transmission electron microscope (TEM), enables production oxide-free Al nanoparticles, which manipulated undergo migration, bonding, rotation, revolution, embedding. The manipulations are facilitated by momentum transfer from takes advantage spiral trajectory magnetic field TEM pole piece. Furthermore, onion-like fullerenes intercalated structures on amorphous carbon films induced through catalytic reactions. δ-, θ-Al2O3 ball/wire hybrid were obtained short time using an flashing mode switches between 1022 e/cm2s. Various α-Al2O3 nanostructures, encapsulated nanoballs or nanorods, also produced. In addition, preparation control Pt, W, Cu nanoparticles achieved higher intensity.
