Available in PDF, EPUB and Kindle. Book excerpt: The propagation of the laser-induced plasma formed by KrF irradiation of Y1Ba2Cu3O-- has been characterized in background pressures of oxygen and argon typically used for thin film growth. The ion current transmitted through the background gases was recorded along the normal to the irradiated pellet as a function of distance in order to measure the decreasing velocity and magnitude of the expanding plasma current due to collisional slowing and attenuation of the laser plume. The integrated ion charge delivered to a substrate at low pressures can be described by elastic scattering giving a general integral cross sections of [sigma]{sub e}(O2) = 3.2 × 10−16 cm2 and [sigma]{sub e}(Ar) = 2.7 × 10−16 cm2. At higher pressures, inelastic scattering leads to increased recombination and reactive conversion of ions indicated by increased fluorescence of all the species, which becomes dominated by fluorescence of YO and BaO. Spatially resolved fluorescence measurements indicate that the luminous boundary to the plasma follows a weak shock front which coincides with the ion flux propagation. The ion transmission is found to drop exponentially with distance and background pressure, in agreement with a simple scattering model which yields general scattering cross sections for ion-argon [sigma]{sub i-Ar} = 2.1 × 10−16 cm2 and ion-oxygen [sigma]{sub i-O{sub 2}} = 2.3 × 10−16 cm2 interactions in background pressures up to 300 mTorr. The general features of the plume deceleration are described in terms of a drag force model. 9 refs., 5 figs.

This book was released on 2012-12-02 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: Containing the proceedings of three symposia in the E-MRS series this book is divided into two parts. Part one is concerned with ion beam processing, a particularly powerful and versatile technology which can be used both to synthesise and modify materials, including metals, semiconductors, ceramics and dielectrics, with great precision and excellent control. Furthermore it also deals with the correlated effects in atomic and cluster ion bombardment and implantation. Part two deals with the deposition techniques, characterization and applications of advanced ceramic, metallic and polymeric coatings or thin films for surface protection against corrosion, erosion, abrasion, diffusion and for lubrication of contracting surfaces in relative motion.

Available in PDF, EPUB and Kindle. Book excerpt: The Symposium on Magnetic Ultrathin Films, Multilayers and Surfaces, hosted by the European Materials Research Society, was held at the Palais de la Musique et des Congré in Strasbourg, France on June 4-7, 1996. Its central theme was the relationship of magnetic properties and device performance to structure at the nano and micrometer length scale. Research on the magnetism of surfaces, ultrathin films and multilayers has increased dramatically during recent years. This development was triggered by the discovery of coupling between ferromagnetic layers across nonmagnetic spacer layers and of the giant magnetoresistance effect in systems of reduced dimension using various micro and nanofabrication techniques has become a subject of special interest. It is certainly the promising application potential of these effects in new magnetic recording device geometries which causes this intensive research, which is done both by companies and at universities and research institutes. A selection of invited and contributed papers presented at the Symposium and accepted for publication is contained in this volume. The contents of these proceedings are organized into seven sections. A. Nanowires, Nanoparticles, Nanostructuring B. Ultrathin Films and Surfaces, Characterization C. Giant Magnetoresistance D. Coupling, Tunneling E. Growth, Structure, Magnetism F. Growth, Structure, Magnetoresistance G. Coupling, Magnetic processes, Magneto-optics. The first four sections contain invited and oral contributed papers in the listed research domains, while the last three sections contain the contributions presented during three large poster sessions.

Download or read book Plasma Production by Laser Ablation PPLA 2003 written by Santo Gammino and published by World Scientific. This book was released on 2004 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume concerns the latest results on pulsed plasma production by energetic laser pulses irradiating solid targets. The produced plasma emits neutrals, clusters, ions, electrons and photons. Plasma properties depend on the laser pulse duration, energy, wavelength, focusing, target nature and irradiation conditions. Plasma expands in vacuum with supersonic velocity and may accelerate heavy ions, with charge states higher than 50+, at energies higher than 10 MeV. This book presents and discusses possible applications, such as ion injection in ECR ion sources, ion implantation, ion post-acceleration and thin film deposition by the PLD technique.
