| The 'finned' LED pixel design includes the glowing zinc oxide fin (purple), isolating dielectric material (green), and metal contact (yellow atop green). The microscopic fins, which the research team arranged into comb-like arrays, show an increase in brightness of 100-1000 times over conventional submicron-sized LED designs. Image: B. Nikoobakht, N.
