Thin Film Growth Simulation Study of Diindenoperylene on aSiO₂ — •Philipp Elsässer and Tanja Schilling — Institute of Physics, University of Freiburg, Germany

The understanding of film growth mechanisms is of high technological importance for growing single crystals, coating surfaces, and film production. By now there is a good understanding of the processes involved in the growth of films consisting of spherical objects, like atoms. In contrast, films of elongated molecules behave with respect to some of their properties in different ways due to their additional rotational degrees of freedom.

The organic semiconductor Diindenoperylene (DIP) is a candidate for organic solar cells or OLEDs. We have investigated an amorphous SiO₂ (aSiO₂) substrate with DIP molecules deposited on the surface. For this, we have performed MD simulations to study the clustering of few DIP molecules on aSiO₂, as well as the molecular orientation in larger groups of DIP molecules.
