Physics of Organic Semiconductors

The field of organic electronics has seen a steady growth over the last 15 years. At the same time, our scientific understanding of how to achieve optimum device performance has grown, and this book gives an overview of our present-day knowledge of the physics behind organic semiconductor devices. Based on the very successful first edition, the editors have invited top scientists from the US, Japan, and Europe to include the developments from recent years, covering such fundamental issues as:

• growth and characterization of thin films of organic semiconductors,
• charge transport and photophysical properties of the materials as well as their electronic structure at interfaces, and
• analysis and modeling of devices like organic light-emitting diodes or organic lasers.
  The result is an overview of the field for both readers with basic knowledge and for an application-oriented audience. It thus bridges the gap between textbook knowledge largely based on crystalline molecular solids and those books focusing more on device applications.

Auteur
Wolfgang Bruetting, University of Augsburg. Professor Brutting received his Ph.D. in Physics from the University of Bayreuth in 1995 with a work on charge transport in one-dimensional charge-density wave systems. He then moved to the field of organic semiconductors where he could take part in the development of organic light-emitting devices for display applications. In 2003 he became Professor for Experimental Physics at the University of Augsburg. His current research activities include thin film growth, photophysics and electrical transport in organic semiconductor devices.

Chihaya Adachi, Kyushu University in Japan. Professor Adachi worked at Chitose Institute of Science and Technology until he joined the Center for Future Chemistry as a Professor. He is heading the Division for Optical Functional Materials which research activities on organic optical electronics range from the synthesis of organic semiconductor materials to the development of devices and the clarification of properties.

Russell J. Holmes is Assistant Professor at the Dept. of Chemical Engineering and Materials Science at the University of Minnesota. His research is primarily focused on the study of thin films and single crystals of organic materials. Russel Holmes is specifically interested in how these materials behave from a growth standpoint, the characterization of their optical and electrical properties, and their performance in optoelectronic devices.
