This book was released on 2007 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: In-situ observations in a transmission electron microscope (TEM) were used to study the microstructure evolution in metal Zr, Pt, Cu, and Au nanocrystalline thin films under ion-beam irradiation. Free-standing films were prepared by sputter deposition. Samples were irradiated in-situ at the Intermediate Voltage Electron Microscope (IVEM) at Argonne National Laboratory with Ar and Kr ions to fluences in excess of 1016 ion/cm2. As a result of irradiation, grain growth was observed in all samples using Bright Field (BF) imaging in the TEM. The average grain size increased monotonically with ion fluence until it reached a saturation value. Similarly to thermal grain growth, the ion-irradiation induced grain growth curves could be best fitted with curves of the type: Dn-;D0n=K?. The irradiations were done at temperatures ranging from 20 to 773 K. The results suggest the existence of three regimes with respect to irradiating temperature: (i) a purely thermal regime, which appears to start above the bulk coarse-grained recrystallization temperature, (ii) a thermally assisted regime where thermal diffusion and irradiation effects combine to increase the rate of grain growth relative to that resulting from either of these mechanisms alone, and (iii) an athermal regime (low-temperature regime) where irradiation can by itself cause grain growth. The transition temperature between the athermal regime and the thermally assisted regime depends on the material, but is in the range 0.14-0.22 times the melting point. The influence of the ion type was also investigated on Zr-Fe irradiated with 600 keV Kr ions versus 600 keV Ar ions.

Available in PDF, EPUB and Kindle. Book excerpt: This book is an introductory manual for Ion Assisted Deposition (IAD) procedures of thin films. It is addressed to researchers, post-graduates and even engineers with little or no experience in the techniques of thin film deposition. It reviews the basic concepts related to the interaction of low energy ion beams with materials. The main procedures used for IAD synthesis of thin films and the main effects of ion beam bombardment on growing films, such as densification, stress, mixing, surface flattening and changes in texture are critically discussed. A description of some of the applications of IAD methods and a review of the synthesis by IAD of diamond-like carbon and cubic-boron nitride complete the book.

Available in PDF, EPUB and Kindle. Book excerpt: While ion-beam techniques have been used to create thin films in the semiconductor industry for several decades, these methods have been too costly for other surface treatment applications. However, as manufacturing devices become increasingly smaller, the use of a directed-energy ion beam is finding novel industrial applications that require the custom tailoring of new materials and devices, including magnetic storage devices, photonics, opto-electronics, and molecular transport. Engineering Thin Films and Nanostructures with Ion Beams offers a thorough narrative of the recent advances that make this technology relevant to current and future applications. Featuring internationally recognized researchers, the book compiles their expertise in a multidimensional source that: Highlights the mechanisms and visual evidence of the effects of single-ion impacts on metallic surfaces Considers how ion-beam techniques can help achieve higher disk-drive densities Introduces gas-cluster ion-beam technology and reviews its precedents Explains how ion beams are used to aggregate metals and semiconductors into nanoclusters with nonlinear optical properties Addresses current challenges in building equipment needed to produce nanostructures in an industrial setting Examines the combination of ion-beam techniques, particularly with physical vapor deposition Delineates the fabrication of nanopillars, nanoflowers, and interconnected nanochannels in three dimensions by using atomic shadowing techniques Illustrates the production of nanopores of varying dimensions in polymer films, alloys, and superconductors using ion-beam irradiation Shows how fingerprints can be made more reliable as forensic evidence by recoil-mixing them into the substrate using ion beams From the basics of the ion-beam modification of materials to state-of-the-art applications, Engineering Th
Download or read book The Effect of DIGM and Irradiation induced Grain Growth on Interdiffusion in Bilayer Ion beam Mixing Experiments written by and published by . This book was released on 1992 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments were performed demonstrating that ion irradiation enhances diffusion-induced grain boundary migration (DIGM) in polycrystalline Au/Cu bilayers. Here, a model is presented relating film-averaged Cu composition in Au with treatment time, grain size and film thickness. Application of this model to the experimental results indicates that irradiation enhances DIGM by increasing the grain boundary velocity. Effects of DIGM and irradiation-induced grain growth on the temperature dependence of ion mixing in bilayers are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the method of ion beam modification of solids in realization, theory and applications in a comprehensive way. It provides a review of the physical basics of ion-solid interaction and on ion-beam induced structural modifications of solids. Ion beams are widely used to modify the physical properties of materials. A complete theory of ion stopping in matter and the calculation of the energy loss due to nuclear and electronic interactions are presented including the effect of ion channeling. To explain structural modifications due to high electronic excitations, different concepts are presented with special emphasis on the thermal spike model. Furthermore, general concepts of damage evolution as a function of ion mass, ion fluence, ion flux and temperature are described in detail and their limits and applicability are discussed. The effect of nuclear and electronic energy loss on structural modifications of solids such as damage formation, phase transitions and amorphization is reviewed for insulators and semiconductors. Finally some selected applications of ion beams are given.
