基本説明
２００９年秋季第70回応用物理学会好評書。
Special emphasis has been made on the difference between inorganic semiconductors such as Si, Ge and GaAs and organic semiconductors (OSC).
Description
(Text)
Organic molecules are currently being investigated with regard to their application as active components in semiconductor devices. Whereas devices containing organic molecules for the generation of light - organic light emitting diodes (OLED) - have already reached the market (they e.g. display information on mobile phones), transistors where organic molecules are used to actively control currents and voltages are still in the development stage.In this book the principle problems related to using organic materials as semiconductors and to construct functioning devices will be addressed.A particular emphasis will be put on the difference between inorganic semiconductors such as Si, Ge and GaAs and organic semiconductors (OSC).

(Author portrait)
Christof Wöll studied physics at the Georg-August University in Göttingen, Germany, and received his Ph.D. degree from the Max-Planck-Institute for Flow Research in 1987. From 1988 to 1989, he worked as a postdoctoral fellow at the IBM Division in San Jose, USA, researching in scanning tunnelling microscopy of clean and adsorbate covered metal surfaces. In 1992 followed his Habilitation in Physics from the University of Heidelberg, where he lectured in physical chemistry. From 1994 to 1996, Professor Wöll was a Heisenberg Fellow of the Deutsche Forschungsgemeinschaft at the Institute of Physical Chemistry, University of Heidelberg. He has published over 180 articles and is a member of the editorial boards of several journals.
