This week on Chemistry Department’s weekly seminar series, esteemed department member Prof. Ulrike Salzner will give a talk titled “A Theoratical Chemist’s View on Materials for Organic Electronics”. All department members and students are cordially invited to attend. Seminar will begin at 12.40 on March 14th, Tuesday, in SB-Z14 (Seminar Room).
Abstract: Theoretical research in the field of organic electronics is supporting experimentalists in their effort to optimize performance of devices such as organic solar cells, organic field effect transistors, and light emitting diodes. Apart from this applied aspect, there are basic research questions related to charge transport mechanism and method development. In the last two decades density functional theory (DFT) has replaced practically all other methods because it is the most accurate theoretical approach for large systems. Nonetheless, all theoretical methods available for calculating systems with more than one electron are approximations and the performance of DFT depends on the density functional. Important results regarding the nature of charge carriers in organic materials, the amount of charge transfer during electronic excitation, charge carrier mobility and so forth depend on the method and can therefore be ambiguous. In my talk I will discuss theoretical issues, give examples for their relevance, and summarize the results of my previous and current research on topics like polaron size, presence or absence of bipolarons, vestigial neutral bands, nature of excited states and singlet fission.
About Ulrike Salzner: Ulrike Salzner received a Dr. rer. nat. from Friedrich-Alexander-Universität Erlangen-Nürnberg in 1993. After post doctoral studies at Northern Illinois University and Memorial University at Newfoundland, she joined Bilkent University as an assistant professor in 1997. She was promoted to associate professor in 2000 and to Full Professor in 2015. Her research interest is theoretical organic chemistry. Currently she is focusing on theoretical investigation of polymers and molecules for organic electronics and singlet fission.
