The structural characterization and EL properties of as-fabricated DUV-LEDs.

Caption

a Schematic diagram of the DUV-LED structure with Gr. b Cross-sectional STEM image of as-grown DUV-LED with Gr and corresponding EDS mapping images of Al, Ga and N elements. c RSM for the (10 5) reflection of the DUV-LED grown on Gr/sapphire. d LOP of the as-fabricated DUV-LEDs with and without Gr as a function of the injection current. e EL spectra of DUV-LED without Gr by varying the injection current from 10 to 80 mA. f EL spectra of DUV-LED with Gr by varying the injection current from 10 to 80 mA.
