Job description This theoretical project concerns the modeling of electronic processes in organic light-emitting diodes (OLEDs). OLEDs have unique properties: they are energy-efficient, have a large area, and can be made flexible and transparent. For these reasons they are considered to be the light sources of the future. OLEDs are presently rapidly entering the display and lighting market. Several mobile-phone brands nowadays offer OLED displays that are superior to the usual LCD displays with backlight. The first white OLEDs for lighting applications are being launched. Essential electronic processes in OLEDs are: 1) the injection of electrons and holes, 2) the transport of electrons and holes, 3) the formation of excitons, i.e., bound electron-hole pairs, 4) the diffusion of excitons, and 5) the decay of excitons under the emission of photons. Many aspects of these processes are still poorly understood. A full breakthrough of OLED technology requires breakthroughs in the modeling of these processes.
Description of the research The research will be part of the project MODEOLED: 'Modeling of organic light-emitting diodes: from molecule to device'. This is a collaborative project between Dutch and German groups and between industry and academia. The academic partners are Karlsruhe Institut für Technologie (KIT) and the Technische Universiteit Eindhoven (TUE). The industrial partners are Philips Research Eindhoven (OLED modules) and BASF-Ludwigshafen (OLED materials). In the project the expertise of KIT and BASF in modeling of the molecular morphology and electronic processes on the molecular level of OLED materials will be combined with the expertise in OLED device modeling at the TUE and in OLED characterization at Philips. The PhD research at the TUE will involve the integration of the knowledge at the molecular level generated at KIT and BASF in the OLED device modeling and the comparison of the modeling with actual OLED devices characterized at Philips. In this way we will achieve a breakthrough in the modeling of OLEDs, where we describe the electronic processes all the way from the molecular up to the device level.
Profile We are looking for a motivated candidate with an MSc in Physics, Chemistry, Materials Science or Mathematics and with strong theoretical and/or computational skills.
