Title:
Amorphous Silicon

by:
 Kazunobu Tanaka (Author), Eiichi Maruyama (Author),
Toshikazu Shimada (Author), Hiroaki Okamoto (Author)

I think you can get this book through your
interlibraray. It discusses all the properties in
detail and also some of good applications of a-Si.
Good luck!!!!!!!

Book Description
Amorphous Silicon Kazunobu Tanaka National Institute
for Advanced Interdisciplinary Research, Ibaraki,
Japan Eiichi Maruyama Hitachi Ltd, Ibaraki, Japan
Toshikazu Shimada Hitachi Ltd, Ibaraki, Japan Hiroaki
Okamoto Osaka University, Osaka, Japan Translated by
Takeshi Sato, National Institute for Advanced
Interdisciplinary Research, Ibaraki, Japan Amorphous
silicon has substantially different properties as
compared to crystalline silicon. It has therefore
become recognized as a fascinating and important
material in its own right, with many interesting
facets that lead to a range of novel and still
developing applications. Amorphous Silicon introduces
the reader to this field by first discussing what is
meant by the amorphous state. It details the way in
which amorphous silicon is prepared, and the growth
mechanism. The main structural, optical and electronic
properties are then covered in detail, and there is a
full chapter on the structural stability of the
material, including photoinduced effects. Finally, a
number of the most exciting applications of amorphous
silicon are presented, including its use in solar
cells, photo-sensors and liquid crystal displays.
Amorphous Silicon will be of great interest to all
those working in solid state physics or chemistry,
materials science and electronic engineering, from
postgraduate students to more experienced workers in
these fields.
