Notizen:
The double-crystal rocking curve of the Si 222 reflection was obtained by a high-resolution technique. The angular half-width of the rocking curve was measured using Mo Kα radiation on a floating-zone-grown silicon single crystal and found equal to 0.07", this value being close to that calculated from the known structure factor of the Si 222 reflection. A refined value for the structure factor was 1.47 (2). For a Czochralski-grown Si single crystal with oxygen concentration .̃1018 atoms cm-3, the angular half-width is higher by a factor of 2.5. The rocking-curve broadening is explained by the presence of oxygen in the silicon lattice.
