Abstract

The fabrication of core-shelled nanowire light-emitting diodes (nanoLED) from core-shell nanowires using pulsed-laser deposition (PLD) was analyzed. High-resolution transmission electron microscopy (TEM) showed the sharp interface between the single-crystal core and the shell. The spatial distribution of the elements in the nanowire was studied using energy-dispersive x-ray spectroscopy (EDS). It was observed that the devices exhibited near band-edge electroluminscence (EL) with a high spectral purity. The internal quantum yield of the sample LED was ∼ 0.01 %.
