Final Report Abstract

The research for this project focused on providing deeper understanding of the growth of complex molecular and hybrid systems. In particular with regard to X-ray scattering during growth we believe to have made substantial progress. We could also use two opportunities which presented themselves during the course of the project. These were first of all the complementary use of machine learning techniques for fast and near-real-time data analysis of surface scattering data. Secondly, we would successfully employ XPCS for the real-time investigation of the dynamics during growth.
