Nanoscale understanding of the dynamics of surface reactions will provide critical information needed to address a variety of materials problems, including corrosion, environmental stability, energy storage, catalysis, and epitaxial film formation. With exciting new developments in novel instrumentation and techniques that can probe dynamic surface and interface reactions in situ from ultrahigh vacuum (UHV) to high-pressure reactive gas environments, a wealth of new insights into these important gas-solid reactions is now being created. The focus of this symposium is on the science of gas-surface reactions at the nanoscale and below, with particular emphasis on forefront in situ characterization of reaction dynamics in “real” environments. The goal is to bring together an interdisciplinary group of experimentalists with expertise in surface chemistry, surface and interface structure, advanced characterization techniques, and surface-dominated applications to discuss timely new advances in the essential mechanisms of surface (and interface) reactions, as determined by dynamic experiments on gas-solid interactions.
Session Topics
Topics appropriate for this session include:
- In situ experiments in the area of gas-solid reactions, such as oxidation (including molecular and atomic oxygen, water vapor, ozone and other energetic oxidizing species) and hydrogen effects (including hydride formation and decomposition, as well as oxide reduction phenomena)
- Surface chemical processes as used in thin-film growth, such as chemical vapor deposition (CVD) and atomic layer deposition (ALD), where the initial stages of the gas reactions (up to the first few monolayers) and the mechanisms of the reactions are emphasized
- Effects of impurities and surfactants on the initial stages of gas-solid reactions
- Novel in situ techniques for structural and/or spectroscopic information on gas-solid reactions, including electron microscopy, synchrotron x-ray scattering, scanning probe microscopy, beam surface scattering techniques, and Rutherford backscattering spectroscopy
