Ion Implantation in Diamond, Graphite and Related Materials


Book Description

Carbon has always been a unique and intriguing material from a funda mental standpoint and, at the same time, a material with many technological uses. Carbon-based materials, diamond, graphite and their many deriva tives, have attracted much attention in recent years for many reasons. Ion implantation, which has proven to be most useful in modifying the near surface properties of many kinds of materials, in particular semiconductors, has also been applied to carbon-based materials. This has yielded, mainly in the last decade, many scientifically interesting and technologically impor tant results. Reports on these studies have been published in a wide variety of journals and topical conferences, which often have little disciplinary overlap, and which often address very different audiences. The need for a review to cover in an integrated way the various diverse aspects of the field has become increasingly obvious. Such a review should allow the reader to get an overview of the research that has been done thus far, to gain an ap preciation of the common features in the response of the various carbon to ion impact, and to become aware of current research oppor allotropes tunities and unresolved questions waiting to be addressed. Realizing this, and having ourselves both contributed to the field, we decided to write a review paper summarizing the experimental and theoretical status of ion implantation into diamond, graphite and related materials.




Graphene


Book Description

Graphene is considered as a miracle material for scientists and engineers owing to its outstanding physical properties. Graphene and its nanocomposites are promising multifunctional materials with improved tensile strength and elastic modulus. graphene nanocomposites may have a wide range of potential applications due to their outstanding properties and the low cost of graphene. Because graphene composites have a controllable porous structure, a large surface area, high conductivity, high-temperature stability, excellent anti-corrosion properties, and composite compatibility, they can be used in energy storage as electrocatalysts, electro-conductive additives, intercalation hosts, and an ideal substrate for active materials. Shortly, graphene will be a base for the next generation’s scientific revolution.

Ion Beam Modification of Materials


Book Description

This conference consisted of 15 oral sessions, including three plenary papers covering areas of general interest, 22 specialist invited papers and 51 contributed presentations as well as three poster sessions. There were several scientific highlights covering a diverse spectrum of materials and ion beam processing methods. These included a wide range of conventional and novel applications such as: optical displays and opto-electronics, motor vehicle and tooling parts, coatings tailored for desired properties, studies of fundamental defect properties, the production of novel (often buried) compounds, and treating biomedical materials. The study of nanocrystals produced by ion implantation in a range of host matrices, particularly for opto-electronics applications, was one especially new and exciting development. Despite several decades of study, major progress was reported at the conference in understanding defect evolution in semiconductors and the role of defects in transient impurity diffusion. The use of implantation to tune or isolate optical devices and in forming optically active centres and waveguides in semiconductors, polymers and oxide ceramics was a major focus of several presentations at the conference. The formation of hard coatings by ion assisted deposition or direct implantation was also an area which showed much recent progress. Ion beam techniques had also developed apace, particularly those based on plasma immersion ion implantation or alternative techniques for large area surface treatment. Finally, the use of ion beams for the direct treatment of cancerous tissue was a particularly novel and interesting application of ion beams.

Graphite Intercalation Compounds II


Book Description

The research on graphite intercalation compounds often acts as a forerunner for research in other sciences. For instance, the concept of staging, which is fundamental to graphite intercalation compounds, is also relevant to surface science in connection with adsorbates on metal surfaces and to high-temperature superconducting oxide layer materials. Phonon-folding and mode-splitting effects are not only basic to graphite intercalation compounds but also to polytypical systems such as supercon ductors, superlattices, and metal and semiconductor superlattices. Charge transfer effects playa tremendously important role in many areas, and they can be most easily and fundamentally studied with intercalated graphite. This list could be augmented with many more examples. The important message, however, is that graphite inter calation compounds represent a class of materials that not only can be used for testing a variety of condensed-matter concepts, but also stimulates new ideas and approaches. This volume is the second of a two-volume set. The first volume addressed the structural and dynamical aspects of graphite intercalation compounds, together with the chemistry and intercalation of new compounds. This second volume provides an up-to-date status report from expert researchers on the transport, magnetic, elec tronic and optical properties ofthis unique class of materials. The band-structure cal culations of the various donor and acceptor compounds are discussed in depth, and detailed reviews are provided ofthe experimental verification ofthe electronic struc ture in terms of their photoemission spectra and optical properties.
