Influence of the organic molecule shape on the molecular surface dynamics

We propose to use coherent X-ray scattering to study the dynamics of organic molecules during organic molecule deposition. Using X-ray photon correlation spectroscopy, we can measure the characteristic time scales over which the surface of the film evolves. To do this, we will study several organic molecules of different shapes to be particularly sensitive to rotational and vibrational degrees of freedom that are not present in inorganic film growth.
