Red to near-infrared emission from InGaN/GaN quantum-disks-in-nanowires LED

The InGaN/GaN quantum-disks-in-nanowire light-emitting diode (LED) with emission centered at ∼830nm, the longest emission wavelength ever reported in the InGaN/GaN system, and spectral linewidth of 290nm, has been fabricated with p-side-down on a Cu substrate.
