Product Description
Divided roughly into two parts, the book describes the physical properties and device applications of hydrogenated amorphous silicon. The first section is concerned with the atomic and electronic structure, and covers growth defects and doping and defect reactions. The emphasis is on the optical and electronic properties that result from the disordered structure. The second part of the book describes electronic conduction, recombination, interfaces, and multilayers… More >>

Amorphous silicon is much harder to model than pure, crystalline silicon. The text goes into much detail about many attempts to do so. The disordered nature gives rise to different electronic and optical properties.
Then adding hydrogen to it increases the complexity of the system. The main allure is for cheap, new materials. Possibly for storage of hydrogen as a fuel. Or such things as solar cells. Currently, a problem with the latter is that most are crystalline, which makes them far more expensive to fabricate. Current proposed manufacturing methods for amorphous silicon are much simpler and cheaper.
The discussion is geared more towards the physicist than the engineer, despite the above motivation. Many of the issues are still ones of pure research rather than development. Overall, the book is optimistic about research and industrial prospects. Much remains to be done.
