非晶形半导体物理学PHYSICS OF AMORPHOUS SEMICONDUCTORS

作者简介

Presenting the fundamentals of amorphous semiconductors, this text should be useful for young scientists intending to develop new preparation techniques for more ideal amorphous semiconductors, such as a-SI:H, to fabricate stable and efficient solar cells and thin film transistors and new artificial amorphous materials such as multilayers for quantum devices. A large portion of the book is devoted to the latest developments of amorphous semiconductors, including new preparation methods for high quality a-Si:H, nature of weak bonds and gap states in a-Si:H, mechanisms for light induced defect creation in a-Si:H and chalcogenides, and quantum phenomena in multilayer films.
