Coherent X-ray measurement of step-flow propagation during growth on polycrystalline thin film surfaces
Abstract
Monitoring growth dynamics of crystalline thin materials progressively is crucial to understand the mechanism. Here, the authors develop a local step flow model to investigate the growth of C60 films on graphene coated over silicon substrates that correlates the step-edge velocity with its terrace lengths using the X-ray photon correlation spectroscopy.
