Summary

The field of semiconducting polymers has attracted many researchers from a diversity of disciplines. Printed circuitry, flexible electronics and displays are already migrating from laboratory successes to commercial applications, but even now fundamental knowledge is deficient concerning some of the basic phenomena that so markedly influence a device's usefulness and competitiveness. This two-volume handbook describes the various approaches to doped and undoped semiconducting polymers taken with the aim to provide vital understanding of how to control the properties of these fascinating organic materials. Prominent researchers from the fields of synthetic chemistry, physical chemistry, engineering, computational chemistry, theoretical physics, and applied physics cover all aspects from compounds to devices. Since the first edition was published in 2000, significant findings and successes have been achieved in the field, and especially handheld electronic gadgets have become billion-dollar markets that promise a fertile application ground for flexible, lighter and disposable alternatives to classic silicon circuitry. The second edition brings readers up-to-date on cutting edge research in this field.

Author Biography

Georges Hadziioannou is Director of the Polymer Department and the European School of Chemistry Polymers and Materials (ECPM) since 2001 at Louis Pasteur University in Strasbourg, France. Prior to this appointment, he spent most of the 80s in the USA, first as postdoc at the University of Massachusetts, then as a research staff member for IBM in San Jos+¬. From 1986 to 1989, he led the Surface and Interface Dynamics group at IBM's Almaden Research Center. Twelve years as professor of polymer chemistry at Groningen University in the Netherlands followed.
He was named Americal Physical Society Fellow in 1994 and received a Humboldt Research Award in 1998. He has authored over 190 scientific papers in peer-reviewed journals, contributed 10 chapters to books and edited the first edition of this book together with P. F. van Hutten in 2000.

George Malliaras studied physics as an undergraduate and did his doctoral research on photorefractivity in polymers. Before joining the faculty at Cornell in 1998, he was a post-doctoral fellow at the University of Groningen (1996) and the Center for Polymer Interfaces and Macromolecular Assemblies (CPIMA), at the IBM Almaden Research Center (1997-98). He is a recipient of the NSF Early Career Development Award, a member of the American Physical Society and of the Materials Research Society.
