Figure 10
(a) USAXS pattern (inset) of an ensemble of gold L-shaped arrays of 2000, 1000, 500 and 200 nm d-spacing (inset), measured using a 6 keV beam of DCM with 4BCC. The line-cut profile taken along the z-axis reveals the primary peak of the array of 1000 nm spacing located at q = 6.3 × 10⁻⁴ Å⁻¹. The minimum detectable q is ∼4.0 × 10⁻⁴ Å⁻¹. (b) A USAXS pattern of a Siemens star pattern (inset), having 25 nm lines and spaces at the center zone. Note that the fine scattering features are differentiable down to q ≃ 0.6 × 10⁻⁴ Å⁻¹.
