Electronic Phenomena in Adsorption and Catalysis on Semiconductors and Dielectrics

It is now firmly established that various adsorptive and catalytic processes taking place on the surface of semiconductors and in MIS structures strongly influence their electronic properties and hence modify the parameters of semi­ conductor devices. The inverse problem of how the semiconductor's electronic subsystem influences adsorption and dissociation of molecules at the surface has been recognized but much less explored. The main purpose of the present book is to generalize the experimental data and explain the relationship be­ tween these two classes of phenomena. We also discuss tentative models of surface electronic states and their interaction with adsorbed molecules. The subject of this book should attract the attention of researchers work­ ing in the overlapping areas of physics and chemistry, and of physics and biology. The research done in this field will help to widen the scope of semi­ conductor applications by finding novel ways of employing surface effects in the construct ion of mi croe 1 ectroni c devi ces, semi conductor gas ana lysers, solar cells, etc. The authors hope that this book will be useful to a wide circle of chemists and physicists concerned with the study of interphase phenomena and questions of adsorption and catalysis. Certain parts of the book will be helpful to physicists and technicians working in rapidly developing branches of semicon­ ductor physics and technology. The book can also serve as a textbook for both under- and postgraduates speci al i zi ng in thi s fi e 1 d.
