Organic molecules adsorbed on inorganic surfaces can form a huge number of different structures on the surface so called polymorphs. These polymorphs have different properties. Which polymorph is formed depends mostly on external parameters like temperature and pressure. To achieve a controlled growth of a specific polymorph with preferable surface properties we can control the system via these external parameters to form new polymorphs. To computationally find out which parameter curve leads us to the desired polymorph we use Optimal Control Theory to calculate the optimal temperature and pressure profiles.
