Abstract Nanocrystalline silicon (nc-Si) thin films have been prepared by a helicon-wave plasma chemical vapour deposition technique on glass-Si substrates. The structural properties and the surface morphology are characterized by Raman spectroscopy, x-ray diffraction and atomic force microscopy. It is proven that the deposited films have the features of high crystalline fraction and large grain size compared with that in the normal plasma-enhanced chemical vapour deposition regime. The crystalline fraction of the deposited films varying from 0% to 72% can be obtained by adjusting the substrate temperature.
