This presentation will meander through events that led to a degree in chemistry, followed by a jump into polymers and processing for silicon devices – from esoteric to practical. And later, thinking about opportunities for flexible electronics enabled by organic and polymeric semiconductors. The path holds both challenges and opportunities. Examples of how managers, mentors and colleagues can influence career choices and directions will be presented. Finally, a view of the impact of morphology on polymer semiconducting performance will be given.
In that regard, to take advantage of the opportunities afforded by flexible, stretchable electronics, semiconducting polymer thin-film morphology must be controlled at multiple length scales; seemingly small process modifications can impact calculated hole mobilities by up to four orders of magnitude. For the readily available semiconducting polymer, poly(3-hexylthiophene) (P3HT), various microstructural features that correlate well with hole mobility have been identified. These include paracrystalline disorder, exciton bandwidth, polymer molecular weight, orientation of crystalline domains, and inter-grain connectivity. Here, a set of general, robust analysis algorithms has been developed to statistically quantify two-dimensional order in microstructures of P3HT-based OFET devices. Insights derived from these studies will help drive the design and development of robust, reproducible flexible, stretchable electronics.
La conférence est pour tout public et le café est servi dès 11h30.
