The Si/SiO2 interface examined by cross-sectional transmission electron microscopy

Abstract
Thin (200–300 Å) cross sections of Si/SiO2 have been examined by transmission electron microscopy at a resolution of better than 10 Å to search for crystalline Si protrusions into, or islands in, the thermally grown SiO2. Within the resolution obtained, no evidence was found for any phase separation within the amorphous oxide layer.
