Journal ArticleDOI
Nitride-based semiconductors for blue and green light-emitting devices
Fernando Ponce,David P. Bour +1 more
TL;DR: In this article, the group III elements of the semiconducting nitrides have been used for the fabrication of high-efficiency solid-state devices that emit green and blue light.
Journal ArticleDOI
High dislocation densities in high efficiency GaN‐based light‐emitting diodes
TL;DR: In this article, the electrical, optical, and structural properties of light emitting diodes (LEDs) fabricated from the III-V nitride material system have been studied.
Journal ArticleDOI
Defects in single-crystal silicon induced by hydrogenation
Journal ArticleDOI
Spatial distribution of the luminescence in GaN thin films
TL;DR: The spatial dependence of the luminescence intensities at the band edge (364 nm) and at the defect-band (centered at 560 nm) regions for epitaxial GaN films have been studied using cathodoluminescence microscopy at room temperature.
Journal ArticleDOI
Luminescence from stacking faults in gallium nitride
TL;DR: In this paper, a direct correlation has been established between stacking faults in a-plane GaN epilayers and luminescence peaks in the 3.29-3.41 eV range, where the structural features of stacking faults were determined by diffraction-contrast transmission electron microscopy, while the optical emission characteristics were observed by highly spatially resolved monochromatic cathodoluminescence.
