Fig. 5. RMS roughness (triangles, right axis); relative ZnO:B haze at 600 nm (diamonds, left axis) and relative haze at 800 nm (squares) as a function of NC-ZnO filling layer thickness on a 1.8 mm thick base ZnO layer (B2H6/DEZ ¼ 4.2 Á 10 À 4). Haze values are normalized to the values of the base layer: 34.5% and 16.1% for 600 nm and 800 nm, respectively.
