摘要
We present direct evidence of an ordered oxide which is epitaxially related to the underlying Si(001) substrate and is distributed throughout thermally grown oxide films with thicknesses between 80 and 1000 Angstrom. This evidence consists of diffraction peaks at the [1,1,0.45] positions. For films with thickness in the range 80-160 Angstrom the integrated intensity of these diffraction peaks increases roughly linearly and the ordered oxide grain size parallel to the surface is constant at 130 Angstrom.
