We report studies of pinning mode resonances in the low total Landau filling (nu) Wigner solid of a series of bilayer hole samples with negligible interlayer tunneling and with varying interlayer separation d. Comparison of states with equal layer densities (p,p) to single layer states (p,0) produced in situ by biasing, indicates that there is interlayer quantum correlation in the solid at smal...

Layered double hydroxide (LDH) single-layer nanosheets were traditionally prepared through a multi-step exfoliation process which is very time-consuming and of low efficiency. Herein we report the preparation of LDH single-layer nanosheets through a facile direct synthesis method. By introducing a layer growth inhibitor, one can directly synthesize LDH single-layer nanosheets instead of LDH lay...

Analyses are given for two three-dimensional lattice systems: A system of close-packed dimers placed in layers of honeycomb lattices and a layered triangular-lattice interacting domain wall model, both with nontrivial interlayer interactions. We show that both models are equivalent to a five-vertex model on the square lattice with interlayer vertex-vertex interactions. Using the method of Bethe...

We are focusing on the developed by us the mathematical analysis methods of the data obtained by three independent spectroscopic techniques and their application to study of atomic and chemical composition profiles across the air-exposed systems SrTiOx/B/Si with interfacial layers (B: SiO2, Si3N4 and HfO2) grown by the atomic layer deposition technique. It was established that the material of t...

It is well established that pad conditioning facilitates polish rate stability in chemicalmechanical polishing (CMP) of interlayer dielectic (ILD) silicon dioxide films and that in the absence of conditioning, polish rates decay over time [Stein et al., Lawing]. ILD rate decay is also associated with changes in pad surface morphology [Lawing, Kojima et al.]. In [Lawing], it was found that the p...

The evolution of magnetic domain structures with temperature during magnetic reversal in Co 4 Å /Pt tPt multilayers with perpendicular anisotropy has been investigated using magneto-optical Kerr imaging. Relatively large Pt layer thicknesses tPt=43 and 63 Å are chosen for this study because the interlayer coupling strength in the multilayers varies from weak at room temperature to strong at low...

In construction industry, laminated glass is more and more used for transparent loadbearing building components. It is known that the residual load-carrying capacity after glass breakage of glass/PVB (polyvinyl butyral) laminates is relatively poor, mainly due to the limited stiffness and strength of PVB. For that reason, the failure behaviour of laminates composed with a stiffer and stronger i...

[1] To understand the role of hydrated clay minerals in active fault systems, a humidity chamber connected to an X-ray diffractometer was used to determine the adsorption of water onto and/or into the crystal structure of smectite. This new type of analysis was carried out under specific temperature and humidity conditions, using powdered clay size fractions (< 2 mm) of rock samples from the Sa...

in this study the characteristics of two different kinds of la0.6sr0.4co0.2fe0.8o3 (lscf) powders, one in-house synthesized powder by a co-precipitation method and another one purchased from fuel cell materials co. (fcm co., usa), were compared. the co-precipitated powder was prepared by using ammonium carbonate as precipitant with a nh4+/no3- molar ratio of 2 and calcination at 1000c for 1 h....

Roles of antisite transition metals interchanging with Li atoms in electrode materials of Li transition-metal complex oxides were clarified using a newly developed direct labeling method, termed powder diffraction anomalous fine structure (P-DAFS) near the Ni K-edge. We site-selectively investigated the valence states and local structures of Ni in Li0.89Ni1.11O2, where Ni atoms occupy mainly th...
