Organic Electronic Fabrication and Investigation of Organic Magnetoresistance

Abstract

The field of organic electronics has advanced in recent years to create new devices for both display and memory-storage technology. Our research investigates organic magnetoresistance (OMAR) in organic semiconductors, specifically organic light emitting diodes (OLED). In the past we have carried out fabrication and measurement at the University of Iowa. To study OLEDs here at UW-Eau Claire requires the design and manufacturing of new equipment and for us to develop creative fabrication methods which take advantage of the facilities we have on campus. A specimen holder was designed using computer aided drafting and modeling and then fabricated using an automated mill and metal lathe. The OLEDs were designed using evaporative deposition techniques for the organic layer (Alq3), the Calcium cathode, and finally an Aluminum coating on an etched indium-tin-oxide coated glass slide. The geometry of the specimens is as such that numerous devises can be placed on a single slide. Lastly, to control our experiment and for data acquisition, a LabView program was utilized.
