MIT's nanowire growth control method could optimize LEDs

Massachusetts Institute of Technology (MIT) researchers used gases to precisely control nanowires' width and composition as they grow, which could yield complex structures optimally designed for particular applications, like LED substrates or solar panels. Nanowires can have very different properties than the same materials in bulk, because of quantum confinement effects, based on the behavior of electrons and phonons within the material. Nanowires may conduct electricity and heat or interact with light in new and useful ways. The high surface-area-to-volume ratio makes nanowires especially useful in sensing applications versus bulk materials.
