Abstract
The influence of rapid-anneal conditions and subsequent coimplantation of oxygen ions on the photoluminescence of erbium ions implanted with an energy of 1 MeV and dose of 5×1014 cm−2 in MOCVD-grown GaN films is investigated. The erbium photoluminescence intensity at a wavelength ∼ 1.54 µm increases as the fixed-time (15 s) anneal temperature is raised from 700 °C to 1300 °C. The erbium photoluminescence intensity can be increased by the coimplantation of oxygen ions at anneal temperatures in the indicated range below 900 °C. The transformation of the crystal structure of the samples as a result of erbium-ion implantation and subsequent anneals is investigated by Raman spectroscopy.
