Photoinduced hysteresis changes and optical storage in (Pb,La)(Zr,Ti)O3 thin films and ceramics

D. Dimos、W. L. Warren、Michael B. Sinclair 等 5 位作者1994-10-01Journal of Applied Physics

Pb(Zr,Ti)O3 and (Pb,La)(Zr,Ti)O3 thin films and bulk ceramics are shown to exhibit two distinct, but related types of photoinduced changes in their hysteresis behavior: (1) a photoinduced suppression of the switchable polarization and (2) a photoinduced voltage shift. Both effects give rise to stable and reproducible…

Structure and defects of an ordered alumina film on NiAl(110)

Jörg Libuda、F.C. Winkelmann、M. Bäumer 等 7 位作者1994-10-01Surface Science

Via oxidation a well ordered Al2O3 film may be grown on an ordered NiAl(110) surface. Its structure has been studied with SPA-LEED (spot-profile analysis) as well as with scanning tunneling microscopy (STM). The oxide overlayer grows strictly two-dimensional with a thickness of close to 5 Å. Double diffraction spots h…

Protein Hydration Observed by X-ray Diffraction

Jiansheng Jiang、Axel T. Brünger1994-10-01Journal of Molecular Biology

Solvation in macromolecular crystal structures was studied by analyzing X-ray diffraction data of two proteins, penicillopepsin and neuraminidase. The quality of several solvent models was assessed by complete cross-validation in order to prevent overfitting the diffraction data. Radial solvent distribution functions…
