Abstract

Fabrication of Organic Light Emitting Diodes in an Undergraduate Physics CourseThin film organic light-emitting diodes (OLEDs) represent the state-of-the-art in electronicdisplay technology. Their uses range from general lighting applications to cellular phonedisplays and high-definition televisions. The ability to produce flexible displays presents anopportunity for a variety of innovative applications. Science and engineering students arefamiliar with displays but typically lack understanding of the underlying physical principles anddevice technologies.We believe that OLEDs provide a valuable context in which to engage science and engineeringstudents in the study of electronic devices. Colleges and universities typically do not have theresources available for students to produce working electronic devices like diodes or transistorsmade from semiconductors like silicon. This paper will describe how science and engineeringstudents, in an upper-level undergraduate physics course, fabricate OLEDs. The active layers ofthe OLEDs are spin-coated onto glass substrates containing a transparent conductive coating.The cathode is formed by the deposition of an appropriate metal contact layer.The deposition and measurement equipment is relatively inexpensive and can be adopted for usein undergraduate physics or engineering courses; as such we believe the topic will be of broadinterest to the physics and engineering community. The paper will discuss the synthesis of thepolymer compounds and the associated deposition techniques. Properties of the devices,including current-voltage characteristics, will be presented along with future plans for thedevelopment of flexible structures on plastic substrates.
