Hematite (alpha-Fe2O3): general characterization, crystal structure, lattice parametersSemiconductorsNon-Tetrahedrally Bonded Binary Compounds IISummary This document is part of Subvolume D 'Non-Tetrahedrally Bonded Binary Compounds II' of Volume 41 'Semiconductors' of Landolt-Brnstein - Group III ...
In our work Ga doped alpha-Fe2O3 samples are well stabilized in alpha phase (rhombohedral crystal structure with space group R3C). Properties of the present composition of Ga doped alpha-Fe2O3 system are remarkably advanced in comparison with recently most studied FeGaO3 composition. At room ...

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 and morphological properties including thickness and roughness of the film are thoroughly investigated to provide a clear explanation on the growth mechanism of alpha-Fe2O3 by AACVD. Results indicate that (110) crystal plane is the predominant factor that influence the formation...

Hematite (alpha-Fe2O3) is one of the best capable photoanode material for water oxidation under visible light. The role of synergetic effect between two metal dopants for enhanced water oxidation is not adequately studied. The mono-doping (Y) and co-doping (Cu, Y) effect on the crystal ...
For alpha-Fe_2O_3 particles, the incorporation of phosphorus into the alpha-Fe_2O_3 structure is suggested, taking into account the mechanism of the crystal growth on the iron(HI) phosphate nuclei (probably amorphous) or some kind of iron(III) phosphate complexes serving as templates in ...
crystal growthmicrostructuresSingle-crystalline α-Fe 2O 3 with a micro-snowflake-like morphology has been synthesized though a hydrothermal reaction in a K 3[Fe(CN) 6] solution without the assistance of any template or surfactant. The morphology and structure of the synthesized hematite were ...
