Fraunhofer-Institut für Organische Elektronik, Elektronenstrahl- und Plasmatechnik FEP
As one of 72 institutes of the Fraunhofer-Gesellschaft, Europe's largest organization for applied research, Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP in Dresden is dedicated to the development of technologies and processes for surface refinement and organic electronics. The Fraunhofer FEP offers a broad spectrum of research, development and pilot production options, in particular for the treatment, sterilization, structuring and finishing of surfaces as well as for OLED micro-displays, organic and inorganic sensors, optical filters and flexible OLED lighting.
zum Thema „Influence of water residue on PVD-deposited metal coatings for Transparent Flexible OLEDs"
Organic electronic devices, such as Organic Light Emitting Diodes (OLED) or Organic Photovoltaic Cells (OPV), commonly consist of electrodes and various functional organic layers. The fabrication of these devices is strictly required to be done in a high vacuum environment, in order to avoid possible reactions between the ambient water/oxygen and organic materials or metal electrodes, which affects the device performance.
Therefore, the goal of this Master-/Diplom-thesis is to find out the influence of water residuals in polymer substrates on the thermally evaporated metal films, as well as the eventual effect on OLED devices. Initial work will focus on the investigation of single metal films, such as Mg, Ag, Mg:Ag, Ca:Ag, etc., and later on the corresponding influence on complete OLED devices.
The work of the thesis is based on the following points and will be determined according to your background:
Introduction to all the topic-related facility and tools (cleanroom, spectrometer, AFM…)
Establishment of a defined scientific description for the water content in substrates
Fabrication of single layer samples or OLED devices
Sample characterization using optical, electrical and morphological methods
Development of models for the relationship between water residuals in substrates and electrode/device properties
The competition is primarily aimed at students of physics, physical engineering, materials science or electrical engineering.
The extent of the work depends on the respective examination regulations of the university. A minimum period of 6 months is desired. The work can be done by both university and Fachhochschule students.
Are you motivated, creative, working independently in an analytical and structured way of working?
You have good MS Office knowledge, good German language skills, very good spoken and written English skills and, above all, enjoy scientific and experimental work?
