Abstract

The dewetting behavior of thin, deuterated polystyrene (dPS) layers on silicon surfaces is investigated. The surface topographics thus produced are investigated with scanning force microscopy and with grazing incidence small angle scattering. Neutrons and X-rays interact differently with this system, producing a reverse of the scattering contrast in the investigated system dPS–Si. For samples annealed above their glass transition temperature a difference in the evolved surface structures is detected as compared with samples stored under toluene vapor. Confined thin films, with a thickness below one-third of the radius of gyration of the unperturbed molecule l

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
