The twin textures of two differently synthesized types of YBa/sub 2/Cu/sub 3/O/sub 7- delta / single crystals, differing strongly in their critical current density (j/sub c/) levels, have been investigated by high-resolution transmission electron microscop ...
Microstructures of three types of YBa/sub 2/Cu/sub 3/O/sub 7- delta / single crystals having strong differences in their j/sub c/ levels have been studied by means of electron microscopy. In order to find any existing relation between the microstructures a ...
The structures of the cubic, the tetragonal and the orthorhombic phases of single crystals of the ferroelectric aluminate sodalite Sr/sub 8/(Al/sub 12/O/sub 24/)(CrO/sub 4/)/sub 2/ were investigated by selected area and convergent beam electron diffraction ...
A subdivision of the stability region of decagonal Al-Co-Ni quasicrystals into eight different structural modifications is presented for the temperature against composition section along the maximum extension of the decagonal phase. The only methods identi ...
A simple method for the preparation of isomorphous xenon derivatives is presented. A device has been designed that allows diffraction studies on protein crystals under xenon gas pressures up to 50 x 10(5) Pa. Crystal mounting and X-ray data collection do n ...
Electron energy loss spectroscopy in a high-resolution transmission electron microscope has recently been used with success to characterize the electronic properties of closed cage nanometer-size graphitic particles. In the plasmon region, the experimental ...
GalnSe(2) single crystals have been grown and characterized by experimental techniques such as high-resolution transmission electron microscopy, x-ray diffraction, x-ray photoelectron spectroscopy and optical and electrical measurements. The samples were p ...
TEM and XRD have been used to characterise the antiferroelectric-ferroelectric phase boundary which exists in the (Pb1-xBax)(Zr1-xTix)O-3 solid solution close to the PbZrO3 end member. Electron diffraction patterns and XRD spectra from the antiferroelectri ...
High-resolution angle-resolved photoemission measurements were performed on single crystals of Bi2Sr2Ca1Cu2O8+delta with different oxygen stoichiometries. The data establish that the gap anisotropy (ratio of the gap along T-M to the gap along T-X) can be r ...
Al-Sn layer structures were prepared by simultaneous evaporation of Al and Sn onto predeposited Al layers prepared on SiO2-covered Si wafer substrates, at a substrate temperature of 470 K and an oxygen partial pressure of 3 X 10(-3) Pa. The chemical state, ...
