Ebook: Properties and Applications of Amorphous Materials

The aim of this NATO ASI has been to present an up-to-date overview of current areas of interest in amorphous materials, with particular emphasis on electronic properties and device applications. In order to limit the material to a manageable amount, the meeting was concerned almost exclusively with semiconducting materials. This volume should be regarded as a follow-on to the NATO ASI held in Sozopol, Bulgaria in 1996 and published as "Amorphous Insulators and Semiconductors" edited by M.F. Thorpe and M.1. Mitkova (Kluwer Academic Publishers, NATO ASI series, 3 High Technology - Vol. 23). The lectures and seminars fill the gap between graduate courses and research seminars. The lecturers and seminar speakers were chosen as experts in their respective areas, and the lectures and seminars that were given are presented in this volume. During the first week of the meeting, an emphasis was placed on introductory lectures while the second week focused more on research seminars. There were two very good poster sessions that generated a lot of discussion, but these are not reproduced in this volume as the editors wanted to have only larger contributions to make the proceedings more coherent.

The particular interest represented in this state of the art survey of amorphous materials is their electronic properties and device applications.
The book is organised in five sections, starting with some more unusual aspects of structure. Section 2 deals with the very new area of self organisation in glasses and how this relates to a glass's rigidity. The next section surveys electronic states and transport phenomena. The fourth section deals with an area of photoinduced effects that has recently seen increased interest due to possible device applications. Finally, section 5 covers some properties specific to amorphous silicon and amorphous carbon.
