Abstract:

Over the last several years, we have demonstrated that mid-infrared laser radiation tuned to the monomer vibrational bands of polymers and organic molecules can be used to deposit thin films for functional devices such as light-emitting diodes. In this talk, I will describe some of the critical experiments, including resonant infrared pulsed laser deposition of insoluble polymers that cannot be spin-coated, such as poly(tetrafluoroethylene) and cyclic olefin polymers. Experiments on several different kinds of mid-infrared lasers are making it possible to benchmark optimal laser parameters for this important regime of thin-film materials processing.
