Book Description
Amorphous, hydrogenated carbon (AHC) films can be deposited on various substrates using several techniques, e.g. plasma deposition and ion beam deposition. The resulting films can be hard, wear resistant and transparent.

Book Description
World experts in amorphous carbon have been drawn together to produce this comprehensive commentary on the current state and future prospects of amorphous carbon, a highly functional material. Amorphous carbon has a wide range of properties that are primarily controlled by the different bond hybridisations possible in such materials. This allows for the growth of an extensive range of thin films that can be tailored for specific applications. Films can range from those with high transparency and which are hard and diamond-like, through to those which are opaque, soft and graphitic-like. Application areas including field emission cathodes, MEMs, electronic devices, medical and optical coatings are now close to market.

Book Description
The electrical and optical properties of diamond-like amorphous carbon films, prepared via the dc glow discharge decomposition of acetylene, show a remarkable dependence on preparation conditions. In particular, as a function of the substrate deposition temperature Td, the room temperature electrical conductivity of the films increases from 10 to the minus 16th power to 10 to the minus 6th power/ohm/cm and the optical energy gap decreases from 2.1 to 0.9eV as Td is increased from 25 to 375 C. The films would have essentially graphitic electrical and optical properties when deposited at Td> or = 400C. For possible semiconductor applications, we have shown that these diamond-like films can be doped n- or p-type via incorporation of P or B atoms during deposition. This doping effect has been confirmed via thermopower measurements. At present we are studying the thermal stability of these films. Results obtained from a study of the effects of annealing on the optical properties of these films will be presented.

Book Description
This book presents the status quo of the structure, preparation, properties and applications of tetrahedrally bonded amorphous carbon (ta-C) films and compares them with related film systems. Tetrahedrally bonded amorphous carbon films (ta-C) combine some of the outstanding properties of diamond with the versatility of amorphous materials. The book compares experimental results with the predictions of theoretical analyses, condensing them to practicable rules. It is strictly application oriented, emphasizing the exceptional potential of ta-C for tribological coatings of tools and components.

Book Description
This book presents the latest research in ultrathin carbon-based protective overcoats for high areal density magnetic data storage systems, with a particular focus on hard disk drives (HDDs) and tape drives. These findings shed new light on how the microstructure and interfacial chemistry of these sub-20 nm overcoats can be engineered at the nanoscale regime to obtain enhanced properties for wear, thermal and corrosion protection – which are critical for such applications. Readers will also be provided with fresh experimental insights into the suitability of graphene as an atomically-thin overcoat for HDD media. The easy readability of this book will appeal to a wide audience, ranging from non-specialists with a general interest in the field to scientists and industry professionals directly involved in thin film and coatings research.
