Abstract: This disclosure relates to the synthesis of Er doped GaN epilayers by in-situ doping by metal-organic chemical vapor deposition (MOCVD). In an embodiment, both above and below bandgap excitation results in a sharp PL emission peak at 1.54 ?m. Contrary with other growth methods, MOCVD grown Er-doped GaN epilayers exhibit virtually no visible emission lines, an present a small thermal quenching effect. The Er incorporation has very little effect on the electrical conductivity of the GaN epilayers and Er doped layers retain similar electrical properties as those of undoped GaN.
