Diamond thin films are deposited on silicon wafers by MPECVD process with the presence of methane, argon, and hydrogen gases. The reaction chamber is designed with an internal microwave reaction cavity and a high-pressure pocket for improving deposition conditions. Scanning electron microscopy reveals tetrahedral and cauliflower-shaped crystals for polycrystalline diamond and nanocrystalline diamond films, respectively. Spectroscopy ellipsometer studies indicate that diamond-like carbon (DLC) films are deposited with a thickness of 700 nm. Fourier transform infrared spectroscopy shows C-H stretching in the range from 2800 cm -1 to 3000 cm -1 . Nanoindentation is performed on DLC films with an average hardness of 10.98 GPa and an average elastic modulus of 90.32 GPa. The effects of chamber pressure, microwave forward power, and gas mixture on the plasma chemistry are discussed. Substrate temperature has a significant influence on film growth rate, and substrate pretreatment can enhance the quality of diamond films.

We are pleased to present the Proceedings of the NATO Advanced Research Workshop “Syntheses, Properties and Applications of Ultrananocrystalline Diamond” which was held June 7-10, 2004 in St. Petersburg, Russia. The main goal of the Workshop was to provide a forum for the intensive exchange of opinions between scientists from Russia and NATO countries in order to give additional impetus to the development of the science and applications of a new carbon nanostructure, called ultrananocrystalline diamond (UNCD) composed of 2-5 nm crystallites. There are two forms of UNCD, dispersed particles and films. The two communities of researchers working on these two forms of UNCD have hitherto lacked a common forum in which to explore areas of scientific and technological overlap. As a consequence, the two fields have up to now developed independently of each other. The time had clearly come to remedy this situation in order to be able to take full advantage of the enormous potential for societal benefits to be derived from exploiting the synergistic relationships between UNCD dispersed particulates and UNCD films. The NATO sponsored ARW therefore occurred in a very timely manner and was successful in beginning the desired dialogue, a precondition for making progress toward the above stated goal. The discovery of UNCD completes a triadof nanostructured carbonswhich includes fullerenes and nanotubes.

CVD diamond films are usually grown using gas mixtures of 1% hydrocarbon (eg CH4) and 99% H2. Diamond films using C[sub 60]/Ar and CH4/Ar discharges are nanocrystalline. Fragmentation of C[sub 60] in Ar discharge occurs via the C[sub 2] pathway. Quantum chemical calculations support the idea that the chemically highly energetic C[sub 2] molecule with adsorption energy=8 eV can grow diamond without intervention of atomic hydrogen, while hydrocarbon precursors with adsorption energies=[similar-to]1 eV require the intervention of atomic hydrogen. The very high nucleation rates are responsible for the nanostructure (crystallite size 15[mu]m) grown from Ar discharges. Diamond nucleation occurs in preference to graphite nucleation as a result of the thermodynamic stability of nanocrystalline diamond.

The exceptional mechanical, optical, surface and biocompatibility properties of nanodiamond have gained it much interest. Exhibiting the outstanding bulk properties of diamond at the nanoscale in the form of a film or small particle makes it an inexpensive alternative for many applications. Nanodiamond is the first comprehensive book on the subject. The book reviews the state of the art of nanodiamond films and particles covering the fundamentals of growth, purification and spectroscopy and some of its diverse applications such as MEMS, drug delivery and biomarkers and biosensing. Specific chapters include the theory of nanodiamond, diamond nucleation, low temperature growth, diamond nanowires, electrochemistry of nanodiamond, nanodiamond flexible implants, and cell labelling with nanodiamond particles. Edited by a leading expert in nanodiamonds, this is the perfect resource for those new to, and active in, nanodiamond research and those interested in its applications.

Dua, former head of the materials science section at the Bhabha Atomic Research Center in India, examines the past, present, and future of diamond thin films. He details their methods of preparation and characterization, and the mechanisms of nucleation, growth, and epitaxy of CVD diamond. Reactor-scale modeling, in situ diagnostics, and the processing of diamond films are some other topics covered. Concluding chapters look ahead to expected applications, recent developments, and new ideas in the field. There is no subject index. Annotation : 2004 Book News, Inc., Portland, OR (booknews.com).

This book is in honor of the contribution of Professor Xin Jiang (Institute of Materials Engineering, University of Siegen, Germany) to diamond. The objective of this book is to familiarize readers with the scientific and engineering aspects of CVD diamond films and to provide experienced researchers, scientists, and engineers in academia and industry with the latest developments and achievements in this rapidly growing field. This 2nd edition consists of 14 chapters, providing an updated, systematic review of diamond research, ranging from its growth, and properties up to applications. The growth of single-crystalline and doped diamond films is included. The physical, chemical, and engineering properties of these films and diamond nanoparticles are discussed from theoretical and experimental aspects. The applications of various diamond films and nanoparticles in the fields of chemistry, biology, medicine, physics, and engineering are presented.
