The Structural and Electronic Properties of Amorphous-silicon-based Alloy Materials
Author: Publisher:
ISBN:
Category : Photovoltaic cells
Languages : en
Pages : 0
Book Description
The research described in this report covers the structure and electronic properties of hydrogenated amorphous silicon and its alloys, emphasizing localized states in the gap and interface states. ESR and photoconductivity studies of prolonged illumination have led to a new model for the Staebler-Wronski effect, in which extra dangling bonds are created as a consequence of recombination. There is new evidence that the effect does not require the presence of impurities. DLTS and optical studies of gap states confirm that the dangling bond states are near mid-gap. Detailed information is presented concerning their role as recombination centers, through luminescence, ESR, and photoconductivity experiments. New localized states associated with phosphorus impurities have been observed by ESR, although their structural identity is not yet known. Time-of-flight measurements of compensated a-Si:H show that although the dangling bond density is low, compensation introduces other states near the band edges that could be boron-phosphorus complexes. Inverse photoemission has measured the conduction band density of states, identifying Si-H antibonding states and the approximate location of the mobility edge. NMR experiments find that thin films of a-Si:H have an excess hydrogen concentration and a new relaxation mechanism observed above 200K with an unknown origin. A wide variety of a-Si:H interfaces have also been studied.

Properties of Amorphous Carbon
Author: S. R. P. SilvaPublisher: IET
ISBN: 9780852969618
Category : Amorphous substances
Languages : en
Pages : 396
Book Description
World experts in amorphous carbon have been drawn together to produce this comprehensive commentary on the current state and future prospects of amorphous carbon, a highly functional material. Amorphous carbon has a wide range of properties that are primarily controlled by the different bond hybridisations possible in such materials. This allows for the growth of an extensive range of thin films that can be tailored for specific applications. Films can range from those with high transparency and which are hard and diamond-like, through to those which are opaque, soft and graphitic-like. Application areas including field emission cathodes, MEMs, electronic devices, medical and optical coatings are now close to market.

Book Description
The Institute for Amorphous Studies was founded in 1982 as the international center for the investigation of amorphous mate rials. It has since played an important role in promoting the und er standing of disordered matter in general. An Institute lecture series on "Fundamentals of Amorphous Materials and Devices" was held during 1982-83 with distinguished speakers from universities and industry. These events were free and open to the public ,and were attended by many representatives of the scientific community. The lectures themselves were highly successful inasmuch as they provided not only formal instruction but also an opportunity for vigorous and stimulating debate. That last element could not be captured within the pages of a book I but the lectures concentrated on the latest advances in the field I which is why their essential contents are he re reproduced in collective form. Together they constitute an interdisciplinary status report of the field. The speakers brought many different viewpoints and a variety of back ground experiences io bear on the problems involved I but though language and conventions vary I the essential unity of the concerns is very clear I as indeed are the ultimate benefits of the many-sided approach.
