Beschreibung

This concise volume provides an introduction to the working principles, design, and construction of air-stable inverted organic light-emitting diodes (OLEDs), which lead to the realization of practical flexible electronics.

The first part of the book reviews the history of the three generations of inverted OLEDs: hybrid organic inorganic light-emitting diodes (HOILEDs), metal oxides and organic electron injection layer, describing the materials, fabrication techniques, device structure, applications, and technological challenges involved in each case. The second part of the book focuses on the carrier injection mechanism in OLEDs.

The book will be of interest to students and researchers working on organic optoelectronics.

Offers the first comprehensive review of the practical air-stable OLED

Written by pioneers and industrial leaders in the field

Provides a careful description of the carrier injection mechanism in organic electronics

Dr Katsuyuki Morii is a principal researcher with the Research Center of Nippon Shokubai Co. Ltd., Japan, and also concurrently serves as an invited professor at Osaka University, Japan. As a visiting researcher at EPFL, Switzerland, he invented the origin of this issue in 2005. Since that time, he is concentrating on air-stable organic electronic devices.   

Dr Hirohiko Fukagawa is a researcher with the Science and Technology Research Laboratories of the Japan Broadcasting Corporation (NHK). His research interests include solid state physics, electronic engineering, organic optoelectronics and flexible displays.
