Theoretical Studies in Epitaxial Stabilization of ZnO-based Light-emitting Semiconductors

Liu P-L, Siao Y-J, Lee M.H., National Chung Hsing University, TW

The device quality ZnO films are expected to next generation materials applied in the field of photo-electronic devices. We find that (0001)-oriented ZnO, Zn0.875Be0.125O, Zn0.875Mg0.125O, and Zn0.875Al0.125O strained layer lattices soften as lattice parameter of [...]

Electroluminescence of ZnO Nanowire/p-GaN Heterojunction Light Emitting Diodes

Wang X., Cole J.J., Jacobs H.O., University of Minnesota, US

ZnO nanowire/p-GaN heterojunction light emitting diodes (LEDs) were fabricated by growing ZnO nanowire vertical arrays in aqueous solution on Mg-doped p-GaN films. Diode-like, rectifying I-V characteristics were recorded at room temperature and a “current crowding” [...]
