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.

Abschluss­ar­beit

zum Thema „Influ­ence of water residue on PVD-depos­ited metal coat­ings for Trans­par­ent Flex­ible OLEDs"

Work­ing field:

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

Require­ments:

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?
