RT Journal Article T1 Study of thermal treated a-Si implanted with Er and O ions A1 Plugaru, R. A1 Méndez Martín, Bianchi A1 Piqueras de Noriega, Javier A1 Tate, T.J. AB Visible luminescence of amorphous silicon layers either implanted with Er or co-implanted with Er and O and subsequently annealed in nitrogen has been investigated by cathodoluminescence (CL) in a scanning electron microscope. Co-implanted samples show a more intense luminescence, which is revealed by annealing at lower temperatures than the samples implanted only with erbium. Thermal treatments cause the formation of erbium oxide as well as Er-Si complexes or precipitates. Violet-blue luminescence has been found from CL images and spectra to be related to Er-Si precipitates. Emission in the green-red range is attributed to oxide species.
