The crystal structure is formed by arranging a plurality of bowl-shaped alpha-Fe2O3 units in a hexagonal array on a silicon chip. The preparation method is to take a template prepared from polystyrene protein as a raw material and to grow the crystal structure by a sol-gel method. The ...
The crystal structure was refined to a bixbyite-type cubic structure (Ia (3) over bar) with alpha = 9.4039(1) angstrom by the Rietveld method. Single crystalline beta-Fe2O3 particles of approximately 1 mu m in size were topotactically transformed into single alpha-Fe2O3 crystals. Electron ...
The alpha-Fe2O3 has shown Rhombohedral (Hematite) crystal structure. Scanning electron microscopy results reveal that the alpha-Fe2O3 thin films have well covered nanoporous surface. The as prepared films exhibited a direct band gap energy varying from 2.36 to 2.14 eV. The alpha-Fe2O3 thin ...

The structure of the basal plane of the a phase of Cr2O3 has been investigated using periodic ab initio Hartree-Fock theory. The Cr-terminated surface, which is nonpolar but is charged, is found to be stable. However, a large-scale relaxation of the surface layer away from the ideal bul...
A study of the crystal structure of Fe2O3in the pressure range up to 65 GPa using synchrotron radiation High-pressure X-ray powder diffraction has been performed on corundum-type αFe2O3 (hematite) in the pressure range up to 65 GPa using synchrotron radiatio... JS Olsen,CSG Cousins,L ...
X-ray photoemission experiments were carried out to study the reaction of water vapor with clean (0001) surfaces of single-crystal corundum (alpha-Al2O3) and single-crystal, thin-film hematite (alpha-Fe2O3) at constant reaction time (3 m... L Ping,T Kendelewicz,Gordon E Brown Jr.,....
