- Recent advances are turning organic displays into
"one of the hottest new areas in the display
Science August 16, 1996, p. 878
- The success of organic semiconductor technologies may become a meter for
the country's ability to answer the increasing demands that consumers make
in the areas of large-area electronics, lightweight displays, and portable
computing. In fact, these two items threaten to merge together in the not
too distant future. In the most likely scenario, consumers will demand lightweight
displays that contain not only the display but also integrate the computing
and input/output circuitry onto one or both sides of a single substrate, such
as a piece of glass or plastic.
- NEW APPLICATIONS
TOOLS: Semiconducting polymers are not only finding numerous new applications,
but they will also make excellent tools to teach students about semiconductor
device concepts and fabrication.
- SURPRISINGLY SIMPLE TECHNOLOGY: A display consists of a film of semiconducting
polymer(s) sandwiched between two electrodes. Polymer LED fabrication usually
begins with a transparent and insulating substrate coated with a transparent
conductor. A spin coating step is used to deposit one or more polymer layers
onto the substrate. After transfer into a vacuum chamber, the top metal electrode
is applied using a vacuum evaporation process.
- PLANS FOR POLYMER ELECTRONICS LAB: An equipment grant from the National
Science Foundation (ECS-9702320) provided the first fabrication equipment,
a vacuum evaporator and a glovebox to protect air sensitive materials. Characterization
equipment is also necessary to measure the electrical properties of the completed
devices current as a function of voltage and the amount of light emitted.
A Cal Poly Plan Project began during Summer Quarter 1998 to assemble and install
a test system for this purpose. A new NSF project (ECS-9820781) began in June
