XPS and XRD study of crystalline 3C-SiC grown by …

1999/5/5· Abstract. Preliminary XPS and XRD studies of the 3C-SiC polycrystals (with the grain size of order of 100 μm) grown by the sublimation method were performed. The XRD data proved a dominant 3C-SiC structure accompanied by an admixture of the residual 6H-SiC phase. The main core-level photoelectron spectra were analysed in detail.

X-Ray Diffraction - Web Mineral

Powder X-ray Diffraction (XRD) is one of the primary techniques used by mineralogists and solid state chemists to examine the physico-chemical make-up of unknown solids. This data is represented in a collection of single-phase X-ray powder diffraction patterns for the three most intense D values in the form of tables of interplanar spacings (D), relative intensities (I/I o ), and mineral name.
