A light bright and tiny: NIST scientists build a better nanoscale LED

The fin LED pixel design includes the glowing zinc oxide fin (purple), isolating dielectric material (green), and metal contact (yellow atop green). Image: B. Nikoobakht / N. Hanacek, NIST

This photo shows a comb-like array of fin LEDs, some of which are glowing (bright spots at tips). Image: B. Nikoobakht / NIST
