There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Jan Blochwitz-NimothJan Blochwitz-Nimoth, Chief Scientific Officer of Novaled, presents a lecture entitled, "Novaled’s conductivity doping technology and materials for Organic Electronic Applications".
The optimization of charge carrier injection and transport is of crucial importance for today’s and future organic electronic applications as Organic light-emitting diodes (OLEDs) and organic photovoltaic devices (OPV). Novaled has established over the last decade the conductivity doping approach as one main method to lower operating voltage and increase power efficiency in OLEDs.
For OLED display applications our work has been focused in the last years on further development of charge carrier transport and doping materials to enhance the crucial blue pixel performance, especially for top emission OLEDs. By the use of the doping technology the performance triangle of Voltage, Efficiency, and Lifetime can be optimized in respect to detailed customer demands.
Another market area for OLEDs is OLED lighting, where a maximum power efficiency is of utmost importance. Since the operating voltage of white PIN-OLEDs is already low at around 3V lately focus was given on further enhancing the out-coupling efficiency of large area flat OLEDs. We developed new organic optical outcoupling enhancement material that can be incorporated in an existing OLED stack without negative impact on device yield. This new material allows scaling of the OLED area and out-coupling effects since it can be deposited by normal large area vacuum coating technologies.
Thirdly such doped charge carrier transport layers can be used in OPV devices, allowing stacking of absorber units and optimizing optical effects inside the OPV stack.
Last but not least doping materials and technology can be used in electronic devices, as organic transistors and diodes.
