Description
For tailoring organic-inorganic interfaces of organic electronic devices controlling the structure that forms during growth is of high importance. Indeed, interface properties often strongly vary for different interface structures. But growing the structure that has the optimal properties for a certain technical application is nothing but trivial, due to the subtle interplay of thermodynamics and kinetics that strongly depend on the growth conditions like temperature and pressure. Therefore, we study how to change temperature and pressure over time in an optimal way to maximize the concentration of a specific high-performance polymorph. The target structure must then be one that is either thermodynamically or kinetically accessible. Finding optimal processing parameters experimentally is a tedious trial and error task, which can be greatly simplified with theoretical guidance. Using the framework of Optimal Control theory, such optimal temperature and pressure protocols can be obtained. In this talk we will demonstrate how this method can be technically implemented, discuss first applications, and point out its possible pitfalls and limitations for the case of designing organic-inorganic interfaces.| Period | 28 Mar 2023 |
