Effect Of SNO2 Overlayer Thickness On Surface Morphology of Pre-Scratched Diamond Thin Films

Artificial diamond achieved great interest from last few decades. This work describes the influence of SnO2 overlayer thickness on nucleation and growth of diamond films on pre-scratched silicon substrates. The SnO2 overlayer was deposited by spray pyrolysis technique and diamond was deposited by Hot Filament Chemical Vapour Deposition (HFCVD) technique. The samples were characterised by Scanning Electron Microscopy (SEM) and Raman spectroscopy.
