We investigated the local layer structures in ferroelectric liquid crystal (FLC) cells which have a monostable switching mode using synchrotron X-ray micro diffraction. The monostable switching mode is realized by the FLC cells filled with a material

The layer structure of the chiral smectic phase showing V-shaped switching was investigated using the X-ray diffraction method. In thin planar cells of a three-component mixture in which V-shaped switching was first reported, the chevron layer struct

Synchrotron X-ray microbeam small angle diffraction experiments were carried out for the characterization of the local layer structure of the narrow wall of a zig-zag defect in a surface stabilized ferroelectric liquid crystal cell. A series of the r

The local layer structure response to the electric field was characterized at and around the broad wall of a zig-zag defect in a surface stabilized ferroelectric liquid crystal cell by a synchrotron X-ray microbeam. The rocking curves were measured a

CoCr thin-film magnetic media used in HDD (hard disk drive) usually show in-plane magnetic anisotropy. We have studied in-plane crystallographic structure of CoCr magnetic films on circumferentially textured and non-textured substrates by grazing inc

Delta-doping is one of the methods to realize high concentration doping in semiconductors, by which the doped atoms are confined in the thin layer in semiconductor crystals. Sb and Er delta doping layers in silicon crystals were grown at different te

The local layer structure of the broad wall of a zig-zag defect in a thin-surface stabilized ferroelectric liquid crystal cell was characterized using a synchrotron X-ray microbeam of less than 5 µm spatial resolution. By using a rocking curve measu

The X-ray absorption fine structure (XAFS) measured with the X-ray fluorescence yield strongly depends on the concentration, thickness and detection geometry resulting from the self-absorption effect. A correction procedure for the self-absorption ef

A synchrotron X-ray microprobe has been applied to XAFS measurements over a small region. Either an ellipsoidal mirror or a modified Kirkpatrick-Baez configuration is used as an X-ray focusing element in combination with a double crystal monochromato
