Figure 2: The optical reflection of 6′′ mc-BSW with surface texture of 600 nm-thick nanorods. Each grain is easily distinguishable by the grain boundary and exhibits the different optical reflections. Two individual grains (grain A and grain B) show the average optical reflections of 5 and 4% in a broad spectrum from 400 to 1000 nm.
