Molecules on Surfaces: Diffusion, Rotation, Self-Assembly, and Chemical Reaction

Dr. Dingyong Zhong, Physikalisches Institut and Center for Nanotechnology, Universität Münster

The studies on molecules-on-surfaces systems are of fundamental importance for organic/molecular electronics and chemical engineering. Due to the high spatial and energy resolution, scanning tunneling microscopy (STM) is a suitable tool to investigate surface-related structures and properties. The studies aim to answer two questions: a) How to tailor surface-supported molecular nanostructures to realize desired functions? b) How to understand the novel mechanical, electronic, electro-optical, and chemical properties of molecular nanostructures with intermolecular and molecule-surface coupling? Here the behaviors of molecules on surfaces, including diffusion and rotation of single molecules, pattern formation of molecular aggregates by self-assembly and self-organized growth techniques, and chemical reaction resulting in the formation of covalently bonded molecular structures, have been studied by STM.
