Two chemical vapor deposition (CVD) systems (hot filament and microwave plasma) and a multitechnique analysis system have been designed, constructed and characterized. The effects of surface steps, substrate material and substrate/filament bias have been examined. Diamond films from outside sources have been analyzed by a variety of techniques. Most notably, numerous defects, especially (111) twins, have been identified by TEM and are similar to those found in natural diamond. Certain diamond particles were in a twinned epitaxial relationship with the Silicon substrate. It has also been found that a thin Silicon carbide layer forms immediately (i.e.

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 includes specific chapters that address film characterization methods and the physics and chemistry of film synthesis. Other topics include deposition chemistry, various techniques for diamond synthesis, diamond heat spreaders, thermal management diamond active electronic devices, and diamond film optics.

The continuing success of the Denver X-Ray Conference is, it seems to me, the consequence of three equally important facets of each meeting. These are: 1) the collegial atmosphere and workshops at which experts and novices mix, talk, and informally share information at many levels; 2) the plenary session at which information is presented that intentionally brings new ideas to attendees to broaden the scope of the field; and 3) the traditional sessions in which interesting reports on current research and applications are presented in a timely and professional way. The first and last of these are discussed separately by Paul Predecki and are organized (no small task!) by the entire advisory board. This requires much more than deciding whether yet another workshop on specimen preparation is needed and whom to prevail upon to organize and present it. In fact, few attendees at these workshops ever appreciate the level of effort that Paul and his staff expend to make sure everything comes off smoothly, even when hundreds of copies of handouts need to be whipped off at the last moment, travel problems arise, or unusual audio visual aids are suddenly needed. But my topic here is the second of the three facets listed above - the plenary session. Organizing this falls to a single individual, on the theory that one person can then approach enough others as speakers to put together a unified and yet diverse program of related and interesting review papers.
