Effect of bias voltage on structural and mechanical characteristics of diamond-like carbon thin film applied by ion beam deposition

This study, investigates the effect of bias voltage on structural changes of diamond-like carbon thin film created by ion beam deposition is investigated. For this purpose, the bias voltage in the values of 0 V, -50 V, -100 V and -150 V on the AA5083 aluminum alloy was considered. Raman spectroscopy was used to evaluate structural. Influence of the bias voltage on the thickness and roughness of...

Formation of silicon nanodots via ion beam sputtering of ultrathin gold thin film coatings on Si

Ion beam sputtering of ultrathin film Au coatings used as a physical catalyst for self-organization of Si nanostructures has been achieved by tuning the incident particle energy. This approach holds promise as a scalable nanomanufacturing parallel processing alternative to candidate nanolithography techniques. Structures of 11- to 14-nm Si nanodots are formed with normal incidence low-energy Ar...

Multi-mev Ion Beams from Terawatt Laser Thin-foil Interactions

We have conducted investigations of a collimated beam of fast protons, produced by a 10TW laser with frequencies of either ω0 (corresponding to 1.053 micron light) or 2ω0 (corresponding to 532 nm light) focused to an intensity of more the 3x10 W/cm onto the surface of a thin-film target. Energies as high as 10 MeV and total number of 10, confined in a cone angle of 40°±10° have been observed. T...

Characterization of nanostructured SnO2 thin film coated by Ag nanoparticles

Nanostructured SnO2 thin films were prepared using Electron Beam-Physical Vapor Deposition (EB-PVD) technique. Then Ag nanoparticles synthesized by laser-pulsed ablation were sprayed on the films. In order to form a homogenous coated of SnO2 on the glass surface, it was thermally treated at 500°C for 1 h. At this stage, the combined layer on the substrate was completely dried for 8 h in the air...
