Multiscale atomistic simulation of metal-oxygen surface interactions: methodological development, theoretical investigation, and correlation with experiment. Final report

Technical Report Judith C. Yang ; Alan McGaughey ; Susan Sinott ; ...

Our long-term vision is for a comprehensive and fundamental understanding of a critical gas-surface reaction, nano-oxidation from the adsorption of oxygen atoms on the metal surface to the coalescence of the bulk oxide via coordinated multi-scale theoretical and in situ experimental efforts. Reaching this goal necessitates close collaborations between theorists and experimentalists, and the development and utilization of unique and substantial theoretical and experimental tools. Achievement of this goal will be a major breakthrough in dynamic surface/interface reactions that will dramatically impact several scientific fields. Many of these are of interest to DOE, such as thin films and nanostructures thatmore »« less

Interface properties of wide bandgap semiconductor structures. Semi-annual technical report

Technical Report Davis, R.F. ; Bedair, S. ; Bernholc, J. ; ...

Ab initio molecular dynamics calculations have shown that the lxl:2H and the 2xl:H surfaces of diamond(C)(100) have a (-) electron affinity(EA); the clean (100) surface has a (+) EA. This is in agreement with experiment. Biased nucleation of C on Beta-SiC(100) and Si(100) has been achieved but not on Cu(100). C nucleation densities on Hf, Ti, Ta, Ni and W were directly related to the carbide heat of formation. The precursors of chlorinated methylsilanes coupled with bias were used to deposit C films on Si(100). Textured C(II) films were also achieved using an oxyacetylene torch.

Ellipsometry of anodic film growth

Technical Report Smith, C.G.

An automated computer interpretation of ellisometer measurements of anodic film growth was developed. Continuous mass and charge balances were used to utilize more fully the time dependence of the ellipsometer data and the current and potential measurements. A multiple-film model was used to characterize the growth of films which proceeds via a dissolution--precipitation mechanism; the model also applies to film growth by adsorption and nucleation mechanisms. The characteristic parameters for film growth describe homogeneous and heterogeneous crystallization rates, film porosities and degree of hydration, and the supersaturation of ionic species in the electrolyte. Additional descriptions which may be chosen aremore »« less

In-situ transmission electron microscopy study of surface oxidation for Ni–10Cr and Ni–20Cr alloys

Journal Article Luo, Langli ; Zou, Lianfeng ; Schreiber, Daniel K. ; ... - Scripta Materialia

The early-stage oxidation of Ni (001) thin films alloyed with 10 or 20 at% Cr at 700 °C has been directly visualized using environmental transmission electron microscopy. Independent of Cr concentration, the oxidation initiates via the nucleation of surface NiO islands and subsurface Cr2O3. The NiO grows and transitions into a continuous film, followed by the nucleation and growth of NiCr2O4 islands through the outer oxide. The Cr concentration plays a more critical role in the later stages of the oxidation. A continuous and more protective Cr2O3 sublayer is established for Ni-20at% Cr, while the Cr2O3 sublayer for Ni-10at%Cr ismore »« less

Assessing Substitution Effects on Surface Chemistry by in Situ Ambient Pressure X-ray Photoelectron Spectroscopy on Perovskite Thin Films, BaCe _x Zr _0.9–x Y _0.1 O _2.95 ( x = 0; 0.2; 0.9)

Journal Article Jarry, Angelique ; Ricote, Sandrine ; Geller, Aaron ; ... - ACS Applied Materials and Interfaces

Performance of proton-solid oxide fuel cells (H+-SOFC) is governed by ion transport through solid/gas interfaces. Major breakthroughs are then intrinsically linked to a detailed understanding of how parameters tailoring bulk proton conductivity affect surface chemistry in situ, at an early stage. In this work, we studied proton and oxygen transport at the interface between H+-SOFC electrolyte BaCexZr0.9–xY0.1O2.95 (x = 0; 0.2; 0.9) thin films and the gas (100 mTorr of H2O and O2) by using synchrotron-based ambient pressure X-ray photoelectron spectroscopy at operating temperature (>400 °C). We developed highly textured BaCexZr0.9–xY0.1O2.95 epitaxial thin films, which exhibit high level of in-planemore »« less
