How metal films de-wet substrates - identifying the kinetic pathways and energetic driving forces
Kevin F. McCarty, John C. Hamilton, Yu Sato +8
We study how single-crystal chromium films of uniform thickness on W(110) substrates are converted to arrays of three-dimensional (3D) Cr islands during annealing. We use low-energ…
Nanoscale periodicity in stripe-forming systems at high temperature: Au/W(110)
J. de la Figuera, F. Leonard, R. Stumpf +2
We observe using low-energy electron microscopy the self-assembly of monolayer-thick stripes of Au on W(110) near the transition temperature between stripes and the non-patterned (…
Labyrinthine Island Growth during Pd/Ru(0001) Heteroepitaxy
Nicolas Rougemaille, Farid El Gabaly, Roland Stumpf +4
Using low energy electron microscopy we observe that Pd deposited on Ru only attaches to small sections of the atomic step edges surrounding Pd islands. This causes a novel epitaxi…
Reduced O diffusion through Be doped Pt electrodes
Roland Stumpf, Clarence Tracy
Using first principles electronic structure calculations we screen nine elements for their potential to retard oxygen diffusion through poly-crystalline Pt (p-Pt) films. We determi…
Reconstructions and faceting of H-covered Al(111)
Roland Stumpf
First principles calculations show that H overlayers induce a honeycomb vacancy reconstruction on Al(111). Above one ML H coverage, Al(111) facets into surfaces vicinal to (111), w…
Ab-initio Calculations of Energies and Self-Diffusion on Flat and Stepped Surfaces of Al and their Implications on Crystal Growth
Roland Stumpf, Matthias Scheffler
Using density-functional theory we investigate several properties of Al(111), Al(100), Al(110), and stepped Al(111) surfaces. We report results of formation energies of surfaces, s…
