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.
Giovanni Nisato, Ton Offermans, Nenad Marjanovic and Rolando Ferrini.
Giovanni Nisato is the Section Head Polymer Optoelectronics of CSEM Basel . His interests cover a wide range of organic semiconductors systems. In his previous positions at Philips Research in the Netherlands, he had the opportunity to lead several innovative projects, ranging from flexible large electronics for display applications to electronically-driven drug delivery devices. Aiming to advance the field of flexible polymer OLED displays, he formed and coordinated the EU-funded FLEXled consortium from 2002 to 2005. Previous polymer science research experience involves governmental lab work at NIST Gaithersburg, USA. Giovanni Nisato holds a PhD. in physics from the ULP Strasbourg, France.
Nenad Marjanovic is working in the Polymer Optoelectronic group at the CSEM’s division in Muttenz, Switzerland in the field of Large Area Printed Electronics. He received the M.S. degree in materials science at the University of Belgrade, Serbia and the Ph.D. degree in technical sciences at the Johannes Kepler University Linz, Austria. Previous to his working with CSEM he co-founded the company plastic electronic GmbH in Linz, Austria and worked with the group of Prof. Reinhard R. Baumann at the Chemnitz University of Technology and the Fraunhofer Institute for Electronic Nano Systems ENAS in Chemnitz, Germany.
Ton Offermans is a senior R&D engineer in the Polymer Optoelectronics Section of CSEM. He studied applied physics at the University of Technology Eindhoven and received his PhD degree in the field of organic photovoltaics. Before joining CSEM he has worked as researcher on light emitting tiles at Materia Nova, asbl. At CSEM he is leading the research on OPV. He is work package leader in the FP7 project SUNFLOWER.
Rolando Ferrini is working as Project Manager at CSEM SA in the Polymer Optoelectronics Group headed by Dr. Giovanni Nisato since 2011. In 1999, he obtained his PhD degree at the UniversitàdegliStudi di Pavia, Pavia, Italy, in theOptical Spectroscopy Group headed by Prof. Giorgio Guizzettiwith a thesis on the optical properties of III-V semiconductor materials for electronics and optoelectronics. From 2000 to 2004, he worked as Research Associate at the Swiss Federal Institute of Technology (EPFL), Lausanne, Switzerland, in the Photonic Crystal Team of the Semiconductor Device Physics Laboratory headed by Prof. Marc Ilegems and Dr.RomualdHoudré, where he studied the optical properties of semiconductor-based photonic crystal devices. From 2000 to 2004, as Senior Research Associate, he joined the EPFL Laboratory of Optoelectronics of Molecular Materials headed by Prof. LiberoZuppiroli, where he was in charge of the activities on organic devices for optics, photonics and lighting. In particular, in the framework of a research agreement between EPFL and ILFORD Imaging Switzerland GmbH, he was responsible for an R&D antenna located on the company site. There, he coordinated the activities of a mixed industrial-academic group (5 R&D engineers and 5 academic researchers) working on the validation and the technology transfer of the ILFORD roll-to-roll printing techniques for optical and lighting applications.
