MIT's nanowire growth control method could optimize LEDs
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.
