Sculptured Thin Films: Accomplishments and Emerging Uses
Akhlesh Lakhtakia
Sculptured thin films (STFs) are nano-engineered materials whose columnar morphology is tailored to elicit desired optical responses upon excitation. Two canonical forms of STFs ha…
Bulk Termination of the Quasicrystalline Five-Fold Surface of Al_{70}Pd_{21}Mn_{9}
Z. Papadopolos, G. Kasner, J. Ledieu +7
The structure of the Al_{70}Pd_{21}Mn_{9} surface has been investigated using high resolution scanning tunnelling microscopy (STM). From two large five-fold terraces on the surface…
Hindered rotation of H2 adsorbed interstitially in nanotube bundles
M. K. Kostov, H. Cheng, R. M. Herman +2
A theoretical study on the rotational dynamics of H2 molecules trapped in the interstitial channels (ICs) of a carbon nanotube bundle is presented. The potential used in this study…
Stochastic Heterostructures in B/N-Doped Carbon Nanotubes
Paul E. Lammert, Vincent H. Crespi, Angel Rubio
Carbon nanotubes are one-dimensional and very narrow. These obvious facts imply that under doping with boron and nitrogen, microscopic doping inhomogeneity is much more important t…
Intrinsic chemical and structural inhomogeneity in lightly doped La(1-x)Sr(x)MnO(3)
Tomohiro Shibata, Bruce Bunker, John Mitchell +1
X-ray absorption fine structure measurements of the Sr and La K edges of the solid solution La(1-x)Sr(x)MnO(3) reveal a consistent deviation from a random distribution of Sr at the…
Effects of annealing time on defect-controlled ferromagnetism in Ga1-xMnxAs
S. J. Potashnik, K. C. Ku, S. H. Chun +3
We have studied the evolution of the magnetic, electronic, and structural properties of annealed epilayers of Ga1-xMnxAs grown by low temperature molecular beam epitaxy. Annealing…
Two-Carrier Transport in Epitaxially Grown MnAs
J. J. Berry, S. J. Potashnik, S. H. Chun +3
Magneto-transport measurements of ferromagnetic MnAs epilayers grown by molecular beam epitaxy reveal the presence of both positive and negative charge carriers. Electrical transpo…
Superconducting properties of nanocrystalline MgB thin films made by an in situ annealing process
X. H. Zeng, A. Sukiasyan, X. X. Xi +11
We have studied the structural and superconducting properties of MgB thin films made by pulsed laser deposition followed by in situ annealing. The cross-sectional transmission…
Tiling of the five-fold surface of Al(70)Pd(21)Mn(9)
J. Ledieu, R. McGrath, R. D. Diehl +4
The nature of the five-fold surface of Al(70)Pd(21)Mn(9) has been investigated using scanning tunneling microscopy. From high resolution images of the terraces, a tiling of the sur…
Thermodynamics of the Mg-B system: Implications for the deposition of MgB2 thin films
Zi-Kui Liu, D. G. Schlom, Qi Li +1
We have studied thermodynamics of the Mg-B system with the modeling technique CALPHAD using a computerized optimization procedure. Temperature-composition, pressure-composition, an…
