Book Description
The effects on the properties of Ta2O5, Al2O3, SiO2 and HfO2 single- and multi-layer optical coatings deposited using ion assisted deposition (IAD) were investigated. IAD is a novel deposition technique which utilizes a separate ion source to direct a beam of ions at the growing film. A Kaufman ion source was used to provide a monoenergetic, neutralized beam of oxygen ions independent of the material evaporation process. The optical and physical properties, as well as laser induced damage threshold (LIDT) values, were studied for coatings bombarded with 200, 300, 500 and 1000 eV oxygen ions at values of current density from 0 to 200 microAmp/sq cm. IAD was successfully applied to deposit coatings at low temperature on heavy metal fluoride (HMF) glass substrates. The coatings deposited using IAD were hard and dense. The IAD coatings improved the durability and abrasion resistance of the HMF glass substrates. The results of this investigation show that IAD can be used to improve the optical and physical properties of optical coatings.

Book Description
An investigation was made by changing the preparation parameters, such as different ion species, ion energy, and ion current density, etc., to determine their effects on refractive indices, absorption, and laser-induced damage threshold, etc. of the coatings of TiO2, ZrO2 and SiO2 whose oxide coatings were prepared by ion-assisted deposition.

Book Description
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.

Book Description
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.

Book Description
Heavy metal fluoride glass materials are attractive for optical applications in the near ultraviolet through infrared wavelength regions. However, many compositions are relatively soft and hygroscopic, and possess low softening temperature (250°C-300°C). We have applied ion assisted deposition (IAD) techniques to deposit MgF2, SiO2 and Al2O3/SiO2 thin film structures on fluoride glass substrates at ambient substrate temperature (100°C). The coatings deposited using IAD improve the environmental durability of the fluoride glass and appear to have reasonably good optical charateristics; without application of IAD, the deposited coatings are not durable and have poor adhesion.
