Abstract:

In this work we report the study of the effect of the deposition parameters on the photoluminescence (PL) intensity of hydrogenated amorphous silicon-carbide (a-SiC:H) films deposited at very low temperature (150 °C) by Plasma Enhanced Chemical Vapor Deposition (PECVD). We have observed that the main deposition parameter that influences the wavelength emission peak is the methane/silane (CH4/SiH4) ratio used for the films deposition, due to a change on the film carbon content. On the other hand the deposition RF power affects the PL intensity, without a change in the PL emission peak. Also we have studied the effect of the film thickness on the PL intensity and we have observed an optimal film thickness.
