Splitting of X-ray diffraction peak in (Ge:SiO2)/SiO2 multilayers
2004年7月1日 · In the (Ge:SiO 2)/SiO 2 multilayers annealed, we observed the splitting (fine structure) of X-ray diffraction (XRD) peak of Ge nanocrystals. In view of the analyses on XRD, Raman scattering results, and transmission electron microscope observations (TEM) we suggest that the splitting of the observed XRD peak originates from compressive stress ...
