Synthesis of diamond from carbon disulfide in hydrogen

The synthesis of diamond has been accomplished from carbon disulfide (CS2) in hydrogen (H-2) using tungsten hot filament chemical vapor deposition, A continuous layer was deposited on silicon and characterized using Raman spectroscopy, X-ray diffraction (XRD), and scanning electron microscopy, The polycrystalline him exhibited a sharp Raman peak at 1331.3 cm(1-) and a broad low-intensity peak at approximately 1500 cm(-1). X-ray diffraction analysis showed peaks corresponding to the {111}, {220}, and {311} reflections of diamond with evidence of [110] texture. Diamond growth from CS2 in H-2 was observed to be highly faceted by scanning electron microscopy.
