tem observation of liquid phase bonded aluminum silicon aluminum nitride hetero interface
Journal of Materials Science, 2011Co-Authors: Christine Marie Montesa, Naoya Shibata, Tetsuya Tohei, Yuichi IkuharaAbstract:Liquid-phase bonded aluminum–silicon/aluminum nitride interface structure was investigated using high-resolution transmission electron microscopy. A textured layer of aluminum formed a stable orientation relationship with aluminum nitride, which showed Al(111) to be tilted by about 4° with respect to the AlN(0001) interface plane. The unique orientation relationship between Al and AlN was predicted as one of the stable orientation relationships using coincidence of Reciprocal Lattice Point method, which surveys the degree of geometrical coherency between two crystals in three-dimensional space. A stable orientation relationship was found to be (001)[1\( \bar{1} \)0]Al//(2\( \bar{2} \)03)[11\( \bar{2} \)0]AlN.

application of coincidence of Reciprocal Lattice Point model to metal sapphire hetero interfaces
Materials Science and Engineering B-advanced Functional Solid-state Materials, 2010Co-Authors: Christine Marie Montesa, Naoya Shibata, Tetsuya Tohei, Kazuhiro Akiyama, Yoshirou Kuromitsu, Yuichi IkuharaAbstract:Abstract Coincidence of Reciprocal Lattice Point (CRLP) model was used to predict the stable orientation relationships of metal/α-Al 2 O 3 hetero interfaces from geometrical considerations. The predicted stable orientation relationships (ORs) between various metals and α-Al 2 O 3 agreed well with the experimentally observed ORs at the hetero interfaces fabricated by film growth processes. In the bcc metal/α-Al 2 O 3 systems with different fabrication processes such as internal oxidation, Burgers and Pitsch–Schrader ORs were experimentally observed, which have not been predicted as the most stable orientation relationships by CRLP. However, these ORs are predicted in CRLP as secondary stable orientations.

Incommensurate spin density wave in metallic V_(2-y)O_3
1993Co-Authors: Wei Bao, C. Broholm, Sue A. Carter, T. F. Rosenbaum, G. Aeppli, S. F. Trevino, P. Metcalf, J. M. Honig, J. SpalekAbstract:We show by neutron diffraction that metallic V_(2-y)O_3 develops a spin density wave below T_N≊9 K with incommensurate wave vector q≊1.7c* and an ordered moment of 0.15μ_B. The weak ordering phenomenon is accompanied by strong, nonresonant spin fluctuations with a velocity c = 67(4) meV A. The spin correlations of the metal are very different from those of the insulator and place V_(2-y)O_3 in a distinct class of Mott-Hubbard systems where the wave vector for magnetic order in the metal is far from a high symmetry commensurate Reciprocal Lattice Point.

Physical review letters, 1993Co-Authors: Wei Bao, C. Broholm, Sue A. Carter, T. F. Rosenbaum, G. Aeppli, S. F. Trevino, J. M. Honig, P. A. Metcalf, J. SpalekAbstract:We show by neutron diffraction that metallic V[sub 2[minus]7]O[sub 3] develops a spin density wave below [ital T][sub [ital N]][approx]9 K with incommensurate wave vector [ital q][approx]1.7[ital c][sup *] and an ordered moment of 0.15[mu][sub [ital B]]. The weak ordering phenomenon is accompanied by strong, nonresonant spin fluctuations with a velocity [ital c]=67(4) meV A. The spin correlations of the metal are very different from those of the insulator and place V[sub 2[minus][ital y]]O[sub 3] in a distinct class of Motte-Hubbard systems where the wave vector for magnetic order in the metal is far from a high symmetry commensurate Reciprocal Lattice Point.
