Nanostructures Research Group CENTER FOR SOLID STATE ELECTRONICS RESEARCH In recent years, there has arisen interest in using organic materials to make soft electronics. The most successful of this is organic LEDs. Since we have not really discussed LEDs in this course, we won’t spend much time on these, but this gives us a good introduction to the “band structure” of organic molecules. (In addition, there are now 3-color flexible organic displays available, as well as white light LEDs made from organic materials.) Following this, we will look at transport in organic molecules, and the possibilities for electronic devices from these materials.

Nanostructures Research Group CENTER FOR SOLID STATE ELECTRONICS RESEARCH We can make LEDs from organic compounds. The earliest ones injected the electrons and holes from the metallic contacts into a single organic material. New ones used doped organics, just as doped semiconductors. Since recombina@on occurs in one organic, this needs a transi@on that emits in the visible.
