Close-packed array improves LED output

Abstract:
Scientists from the University of Hong Kong used a nanopatterned mask to etch the surface on an LED. According to the researchers, the mask is composed of air holes between hexagonal-close-packed microspheres and could be a low-cost alternative to e-beam writers

"It takes just 5 ml of a 1% silica microsphere suspension, which costs only tens of dollars, to coat a 2 inch wafer," Anthony H W Choi of the university's department of electrical and electronic engineering told nanotechweb.org. "Compared with the huge investment of an e-beam writer, high maintenance costs and expensive electron resists, microsphere lithography is a cheap and practical nanotechnology."
