Direct Printing of Organic Electronics at the Nanometer Scale

摘要

We explore new methods for direct patterned growth of organic semiconductor thin films useful in organic electronic devices. The scope of the program ranged from the growth of patterns from the nanometer to the centimeter scales. Its objectives included developing new tools and analytical techniques for the fabrication of organic nano and microstructures, to the study of such low dimensionality nanostructures for their interesting and potentially useful optoelectronic properties. The work included fundamental theoretical and experimental investigations of the limitations to growth at the smallest dimensions, and applying these findings to the demonstration of practical organic electronic devices. We demonstrate direct patterning of very high performance electrophosphorescent organic light-emitting devices and scaling up of the printing apparatus for direct patterning of multiple devices simultaneously.
