Introduction to Flexible Electronics
Since the discovery of organic materials with conducting properties, about three decades ago, organic optoelectronics has evolved into a dynamic field of applied research and industrialization. Due to their outstanding material properties compared to traditional inorganic semiconductors, organic semiconductors are anticipated to impact strongly on the future development of semiconductor technology. For example, polymer semiconductor devices are mechanically flexible, comparatively easy to process at low-cost allowing customer-designed manufacturing. A bright future is forecasted for organic LEDs. Various applications ranging from organic displays, organic solid-state-lighting, to integrated sensor systems are expected to produce a huge impact on our future daily life. In this lecture a survey on organic optoelectronics will be presented by exposing the participant to the basics of organic-LEDs, -photodetectors, -field-effect transistors and their combination to integrated systems. The device physics and required production technologies like screen-, ink-jet-, gravure-printing of polymeric semiconductors materials will be discussed in the context of potential future applications and markets.
The course addresses a technologically interested audience coming from industry as well as from universities.

Dr. Nenad Marjanovic received the MSc. Degree in Materials Science at the Faculty of Electrical Engineering, University of Belgrade, Serbia. After that, he joined the group of Prof. Niyazi Serdar Sariciftci at Johannes Kepler University Linz, Austria, where he received the PhD. Degree in Technical Sciences. The device physics and photo-induced effects in organic thin film transistors and diodes were in the focus of his scientific activity. At the end of 2005 he co-founded the company plastic electronic GmbH in Linz, Austria, where he held a CTO position. During that period he and his team developed the technology for the fabrication of organic electronic devices (e.g. OTFTs and diodes) in a roll-to-roll manufacturing fashion combining printing and vacuum evaporation. In 2009 he joined the group of Prof. Reinhard R. Baumann at Chemnitz University of Technology and Fraunhofer Institute for Electronic Nano Systems ENAS in Chemnitz, Germany, where he worked on developing the technology for low temperature curing of printed amorphous metal oxides on the substrates commonly used in Printed Circuit Board (PCB) industry. In 2011 he joined CSEM Muttenz, Switzerland, where he is currently taking the position of a Project Manager. His research focus is on large area flexible and hybrid electronics. Dr Marjanovi? has published more than 22 peer-reviewed papers in the high level scientific journals, which are cited more than 1000 times. Last but not least, in 2010 he was awarded with the Serbian National Prize “Nikola Tesla” for Science and Technological Innovations by the Serbian Government.
