Oxygen-Enhanced 1.54µm Photoluminescence of Er+3 In Silicon
Published online by Cambridge University Press: 21 February 2011
Abstract
Favennec et al. (Jap. J. Appl. Phys. 29, L524, 1990) reported that the 1.54µm photoluminescence of Si implanted with Er+3 is activated by oxygen impurities. We observe a significant enhancement in the luminescence in Er-doped silicon epitaxial layers MBE-grown with intentional oxygen contamination. The PL is shown to be a bulk property of the material as it persisted after a partial layer removal by wet etching.
