Book Description
A comparative study of ArF- and KrF-laser generated carbon plasmas has been performed under pulsed laser deposition conditions of amorphous diamond-like carbon (DLC) films. Gated-ICCD species-resolved imaging, luminescence spectroscopy and ion probe diagnostics have revealed distinct differences between the carbon plumes generated by ArF- and KrF-lasers. KrF-laser (6.7 J/cm2) irradiation produces a less energetic carbon plasma containing larger amounts of luminescent C2 compared with ArF-laser ablation at the same energy fluence. Spectroscopic ellipsometry and EELS analysis of the DLC films deposited on Si 100 and NaCl substrates were utilized to characterize the high quality ArF- and KrF-laser deposited films (up to 84% of sp3 bonded carbon for 7 J/cm2-ArF-laser DLC film). The more energetic and highly-atomized ArF-laser carbon plasma appears to be responsible for the better diamond-like properties.

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 contains the proceedings of the largest conference ever held on this subject. The strong interest in this field is largely due to the fact that both fundamental aspects of laser-surface interaction as well as applied techniques for thin film generation and patterning were treated in detail by experts from around the world.

Book Description
The third method invented is called the Rolling-assisted-biaxially-textured-substrates (RABiTS). The book is divided into four sections. The first section discusses the three methods to fabricate biaxially textured substrates, upon which, epitaxial YBCO or other HTS materials can be deposited to realize a single-crystal-like HTS wire. The second section includes chapters on various methods of HTS deposition such as pulsed laser ablation (PLD), thermal co-evaporation, sputtering, pulsed electron beam deposition, ex-situ BaF2 by co-evaporation flowed by annealing, chemical solution based ex-situ processes, jet vapor deposition, metal organic chemical vapor deposition (MOCVD), and liquid phase epitaxy (LPE). The third section includes detailed chapters on other HTS materials such as the various Tl-based and Hg-based conductors. These Second-Generation HTS conductors, also referred to as "Coated conductors" represent one of the most exciting developments in HTS technology.

Book Description
Laser processing has been used in a wide variety of applications and materials such as semiconductors, superconductors, ceramics, polymers and metals. Lasers provide a controlled source of atomic and electronic excitations involving nonequilibrium phenomena that lend themselves to processing of novel materials and structures. The range of laser-solid interactions involving electronic excitation, melting and evaporation result in the formation of novel phases, selective gas excitations, surface modification and low-temperature thin-film deposition. This book from MRS focuses on the use of lasers in both the fundamental understanding and applied aspects of laser-solid and laser-gas interactions relevant to materials processing. Applications featured include thin-film transistors formed by laser-induced crystallization of amorphous silicon, diamond coatings and micromachining. Topics include: fundamentals of laser-solid interactions; fundamentals of pulsed laser ablation; pulsed laser deposition; novel applications of laser processing; laser-driven formation of nanocrystals; laser annealing; surface modification and etching; and laser-assisted chemical vapor deposition.

Book Description
We have deposited hydrogen-free diamond-like amorphous carbon (amorphous diamond) films by ArF (193 nm) pulsed laser ablation of graphite. The deposition process is performed with the laser power density of only 5x10(8) W/cm2 at room temperature without any auxiliary energy source incorporation. The resulting films possess remarkable physical, optical and mechanical properties which are close to those of diamond and distinct from the graphite target used. The films have a mechanical hardness up to 38 GPa, an optical energy band gap of 2.6 eV and excellent thermal stability. Analysis of electron energy loss spectroscopy reveals the domination of diamond-type tetrahedral bonding structure in the films with the Sp3 bond fraction over 95%. Compared to other reported results of pulsed laser deposited diamond-like carbon films, our experimental results confirm that the laser wavelength or photon energy plays a crucial role in controlling the properties of the pulsed laser deposited diamond-like carbon films.
