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.

Strain relaxation analysis of LaAlO3/SrTiO3 heterostructure using Reciprocal Lattice mapping
Applied Physics Letters, 2012Co-Authors: Wei Wei, Alp SehirliogluAbstract:Strain-relaxation in LaAlO3/SrTiO3 heterostructures was systematically investigated with LaAlO3 film thickness in the range 4.9-84 nm. Heterostructures were characterized using Reciprocal Lattice mapping (RLM), high resolution rocking curve, and x-ray reflectivity. RLM enables the measurement of Lattice constant with accuracy of 10−6 nm. Lattice constant, mismatch, and strain are independently determined in both out-of-plane and in-plane directions. Heterostructures are tetragonally distorted over the entire range of film thickness, even in the film with thickness of 84 nm, in which plastic deformation occurred. This strain-relaxation analysis of LaAlO3/SrTiO3 heterostructure contributes, on the experimental basis, to the knowledge of the strained heterostructure interfaces from thin film growth point of view.

Synchrotron spike topography of natural Type IA diamond
Diamond and Related Materials, 1993Co-Authors: Moreton Moore, Richard G. Waggett, Wojciech K. Wierzchowski, A.p.w. MakepeaceAbstract:Abstract Natural Type Ia diamond contains impurity platelet precipitates of only a few atoms thick and of diameters typically 10–100 nm, lying on {100} planes. Such platelets produce 〈100〉 spikes in diffraction associated with some Reciprocal Lattice points. They are very weak and long exposures are needed to record them. Hitherto, X-ray topographic studies of Reciprocal Lattice spikes in diamond have concentrated upon the strong 111 reflexion, which is surrounded by six spikes; but here we have studied with powerful synchrotron radiation the two spikes emanating from the weaker 331 reflexion. This has the advantage that only one spike at a time, rather than three, is intersected by the Ewald sphere; and consequently, only one image is recorded, rather than three (possibly overlapping) ones. We have discovered that the intensity of these spikes follows an inverse 3 2 power law with distance from the 331 Reciprocal Lattice point, whereas an inverse square law had been expected. Associated with platelets are voidites. These are {111} faceted defects of low electron density; and in certain diamonds, sheets of voidites replace platelets. Spikes in the 〈111〉 directions from the 111 Reciprocal Lattice point appear to arise from voidite sheets, and we have observed weak 〈111〉 spikes emanating from the 331 Reciprocal Lattice point.
