Figure 3: The optical reflection of 6′′ mc-BSWs with different nanorod lengths. The average length on BSWs distributes from 100 nm to 1 μm. The reflection is approximately inversely proportional to the average nanorod length. The reflection is about 9.5% for BSW decorated with 100 nm-thick nanorods and suppressed to 2% for BSW with 1 μm-thick nanorods.
