Abstract

original image

Inorganic light-emitting diodes (LEDs) that can be tuned continuously from red to blue are fabricated using multifacetted GaN nanorods with InGaN/GaN quantum well layers. The layer thickness naturally varies as they are deposited on the multi-faceted nanorods. On page 3284, Gyu-Chul Yi and co-workers show that when the current traveling through layers of different thickness is altered, the color of light emitted from the nanorod LED changes.
