Diffraction from Oxide Superlattices - Stacking Sequence Effects in Plan View

Quantitative X - ray diffraction from superlattices i 1 11

We have developed a structural refinement method which allows the quantitative determination of structural disorder in superlattices. We present first a number of model calculations which give counterintuitive results. One such model calculation implies that structural disorder broadens diffraction line widths contrary to naive expectation. This then forms the basis for structural refinement in...

Engineering correlation effects via artificially designed oxide superlattices.

Ab initio calculations are used to predict that a superlattice composed of layers of LaTiO3 and LaNiO3 alternating along the [001] direction is a S=1 Mott insulator with large magnetic moments on the Ni sites, negligible moments on the Ti sites and a charge transfer gap set by the energy difference between Ni d and Ti d states, distinct from conventional Mott insulators. Correlation effects are...

Stacking Class Probabilities Obtained from View-Based Cluster Ensembles

In pattern recognition applications with high number of input features and insufficient number of samples, the curse of dimensionality can be overcome by extracting features from smaller feature subsets. The domain knowledge, for example, can be used to group some of the features together, which are also known as “views”. The features extracted from views can later be combined (i.e. stacking) t...

Global Optimization of Stacking Sequence in a Laminated Cylindrical Shell Using Differential Quadrature Method

Based on 3-D elasticity approach, differential quadrature method (DQM) in axial direction is adopted along with Globalized Nelder–Mead (GNM) algorithm to optimize the stacking sequence of a laminated cylindrical shell. The anisotropic cylindrical shell has finite length with simply supported boundary conditions. The elasticity approach, combining the state space method and DQM is used to obtain...
