Controlled Synthesis Of Diamond Films Using A Microwave Discharge Non Equilibrium Plasma

The Diamond Films Handbook is an important source of information for readers involved in the new diamond film technology, emphasizing synthesis technologies and diamond film applications. Containing over 1600 references, drawings, photographs, micrographs, equations, and tables, and contributions by experts from both industry and academia, it inclu

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.

Ultrananocrystalline Diamond: Syntheses, Properties, and Applications is a unique practical reference handbook that brings together the basic science of nanoscale carbon structures, particularly its diamond phase, with detailed information on nanodiamond synthesis, properties, and applications. Here you will learn about UNCD in its two forms, as a dispersed powder made by detonation techniques and as a chemical vapor deposited film. You will also learn about the superior mechanical, tribological, transport, electrochemical, and electron emission properties of UNCD for a wide range of applications including MEMS, NEMS, surface acoustic wave (SAW) devices, electrochemical sensors, coatings for field emission arrays, photonic and RF switching, biosensors, and neural prostheses, and more. This ôEverything about Ultra-nanocrystalline Diamondö book with 16 chapters is written by leading experts worldwide. It is for everyone who researches carbon nanostructures, everyone who produces them, everyone who characterizes them, and everyone who builds devices using them.

For the first time, this comprehensive handbook presents the emerging field of microwave technology for the synthesis of nanoparticles. Divided into three parts--fundamentals, methods, and applications--it covers topics including microwave theory, scale-up, microwave plasma synthesis, characterization, and more. This offers both an important volume for academic researchers, and a resource for those in industry exploring the applications of nanoparticles in semiconductors, electronics, catalysis, sensors, and more.
