This book reviews the current understanding of electronic, optical
and magnetic properties of conjugated polymers in both the
semiconducting and metallic states. It introduces in particular
novel phenomena and concepts in these quasi one-dimensional
materials that differ from the well-established concepts valid for
crystalline semiconductors. After a brief introductory chapter, the
second chapter presents basic theore tical concepts and treats in
detail the various models for n-conjugated polymers and the
computational methods required to derive observable quantities.
Specific spatially localized structures, often referred to as
solitons, polarons and bipolarons, result naturally from the
interaction between n-electrons and lattice displacements. For a
semi-quantitative understanding of the various measure ments,
electron-electron interactions have to be incorporated in the
models; this in turn makes the calculations rather complicated. The
third chapter is devoted to the electrical properties of these
materials. The high metallic conductivity achieved by doping gave
rise to the expression conducting polymers, which is often used for
such materials even when they are in their semiconducting or
insulating state. Although conductivity is one of the most
important features, the reader will learn how difficult it is to
draw definite conclusions about the nature of the charge carriers
and the microscopic transport mechanism solely from electrical
measurements. Optical properties are discussed in the fourth
chapter."
