Electron Diffraction of Erbium Silicides

Table 977. Electron diffraction of erbium silicides.

Erbium silicides Electron diffraction
ErSi2-x Orientation relationship of (10-10)YbSi2-x/(11-2)Si
Diffraction pattern of a planview TEM sample of ErSi2-x on Si(001) annealed at 700 °C. The extra spots are due to ordered vacancy structure are marked by "O". [1]
Orientation relationship of (10-10)YbSi2-x/(11-2)Si
Schematic plots showing: (a) the ordered vacancy structure, (b) a simulated electron diffraction pattern viewed along the [1-100] silicide direction and (c) three-dimensional vacancy ordering structure. The vacancy positions are indicated as empty squares. [1]
Orientation relationship of (10-10)YbSi2-x/(11-2)Si
Diffraction pattern of a cross-sectional TEM sample of ErSi2-x on Si(001) annealed at 700 °C. [1]
