Sažetak
Thin film structures consisting of nano- crystalline and amorphous silicon layers deposited on glass by plasma enhanced chemical vapour deposition have been studied by optical spectroscopy methods (transmittance, photo-thermal deflection spectroscopy and photocurrent spectroscopy) while structure was examined by Raman spectroscopy. The nano-crystalline layers were grown on the same amorphous layers, using different radio-frequency (RF) discharge powers, leading to different structural and optical properties. The energy dependence of the absorption coefficient above the band gap agrees well to the bimodal size distribution of crystals and crystal fraction estimated by Raman spectroscopy. For energies below the band gap, the comparison of the absorption of the bilayer systems with respect to single amorphous layer reveals that the samples produced at higher RF discharge present a higher disorder degree (Urbach edge increases) and higher number of structural defects (absorption related to the defects increases).
