Figure 4
Magnified view of the reconstructed phase of the transmission function resulting from (a) step and (b) fly scans, with a comparison with an SEM (c) of the specimen, taken from the box in Fig. 2(d). We can clearly see the inner end of the 100 nm bar (arrows). The circle in (c) highlights the 60 nm layer of Cr which remained after manufacture; however, the SXDM images clearly resolve the Au beneath. |
