2300. MIYAKE, S. Orientations of Metallic Crystals, Formed by the Evaporation Method. I. Iron Crystals Formed on the Cleavage Plane of Zinc Blende. Proc. Phys. Soc. (Japan), vol. 1, 1946, pp. 6-11; Chem. Abs., vol. 44, 1950, p. 9207. Electron-diffraction experiment of a film of Fe crystals, formed by the evaporation method on the cleavage plane of Zn blende, was made. The orientation of the Fe crystals in the film depends upon the temperature of the Zn-blende crystal at the time of the film formation, because the temperature affects the quantity of gas molecules absorbed in the Zn-blende crystal. Heating after the formation of the Fe crystals has no effect on their orientations. The film formed at high temperatures or heated after their formation gives irrational spots or mesh pattern in the electron diffraction. This is attributed to finely repeated twins of the Fe crystals. |
