IR laser-induced CVD of β-Sn/SnSi-nanodisperse alloys from stannane–silane mixture

TEA CO2 laser-irradiation of equimolar stannane–silane mixture in Ar results in thermal decomposition of both gaseous compounds and chemical vapour deposition of nanostructured films that were analyzed by FTIR and Raman spectroscopy, X-ray diffraction and electron microscopy and shown as composed of crystalline β-Sn nanobodies in amorphous Sn/Si alloy. The co-pyrolytic formation of the Sn/Si alloy involves intermixing/clustering of simultaneously extruded Si and Sn atoms in the gas phase and represents one of few special techniques allowing formation of this rare material.
