Optical and Transport Properties

Upendra Harbola is currently a Postdoctoral Fellow in University of California at Irvine. He received his M.Sc. in 1996 from Kumaon University (India) and his Ph.D. in 2003 from Jawaharlal Nehru University (India) where he worked with Professor Shankar P. Das on glass transition phenomena in binary liquids. Presently his research interests include the development of theoretical tools to study the equilibrium and non-equilibrium response functions for optical and transport properties of many electron systems. 

It usually happens that fundamental research in the sciences of materials follows rather than precedes technological application. Thus the commercial success of xerography (Dessauer and Clark, 1965) retroactively stimulated extensive basic investigation of the optical and transport properties of... 

After dealing in some detail with the optical and transport properties of amorphous semiconductors, we include a chapter on some of their applications in practical devices. We believe that it is of general interest to the reader to learn about the physical principles of various devices based on amorphous semiconductors. It should sJso be a stimulating reading on a field whose future depends much on further ingenuity in applied research. This remark does not mean that a deeper understanding of the fundamentals should be underestimated. It is well known what a difference it made in the crystalline semiconductor technology in the fifties compared with the thirties.

The Cu S film plays an important role in photovoltaic operation. It acts as an absorbing layer where the minority carriers are created by interaction with the incident radiation and where the transport to the junction takes place. Hence the Cu S film requires maximum cpntrol and reproducibility of optical and transport properties which in turn strongly depend on chemical composition, film thickness, grain size and interface states between Cu S and CdS. Hence special interest has to be directed towards technology and diagnostics of Cu S films. 

Some Electrical, Optical, and Transport Properties of the Mixtures The relative permittivity and the dynamic viscosity of binary mixtures of water with cosolvents are also relevant to the solvation and behavior of electrolytes and ions in these mixtures. These, again, are intensive properties, so that rather than dealing with excess quantities deviations from ideal behavior according to eq. (3.43), with AT replacing i , should be used.
