Figure 4
(a) TSAXS images from a Langmuir monolayer of AuNPs at the air–water meniscus interface against a vertically immersed Si substrate. The monolayer surface pressure was 7 mN m−1, corresponding to the meniscus-edge height of hmax = 3.6 mm. (b) TSAXS images measured after raising the Si substrate by 4.5 mm, leading to Langmuir–Blodgett deposition of the AuNP monolayer onto the substrate. |
