Abstract

Light emitting diodes were grown by molecular beam epitaxy using NH, as nitrogen precursor. The active layer is composed by a single plane of undopedInGaN layer with about 15% of In. The structure was buried by 2700 Angstrom of Mg-doped GaN (p = 1 x 10(17) cm(-3)). The turn on voltage is at 4.5 V and the operating voltage is 6.1 V at 20 mA. Temperature dependent I(V) characteristics reveal the predominance of tunneling injection current. We measure room temperature electroluminescence in the blue from 440 to 490 nm with a narrow full width at half maximum. (C) 2001 Elsevier Science B.V. All rights reserved.
