Download scientific diagram | (a) Left: representative SEM image of silica opal on a patterned Si substrate with complex geometry. Right: Fourier transform of a marked region (about 17 spheres × 17 spheres) in an SEM image. (b) Left: SEM image of the same silica opal on another area of the patterned Si substrate. Right: Fourier transform of a marked region (about 38 × 10 spheres) in an SEM image. (c, d) Fourier transform of Figure 1a. (c) Large marked region (about 70 μ m × 50 μ m). (d) Small marked region (about 10 spheres × 10 spheres).  from publication: Integration of Self-Assembled Three-Dimensional Photonic Crystals onto Structured Silicon Wafers | We report on the fabrication of high-quality opaline photonic crystals from large silica spheres (diameter of 890 nm), self-assembled in hydrophilic trenches of silicon wafers by using a novel technique coined a combination of "lifting and stirring". The achievements reported | Silicon Wafer, Photonic Crystals and Self-Assembly | ResearchGate, the professional network for scientists.
