SEM micrographs for the fabricated ZPs. (a) Overview of the HSQ-ZP template with a diameter of 300 µm, t = 1000 nm. (b, c) SEM images at a tilt of 45° of the HSQ-ZP. (d, e) SEM images at a tilt of 45° of the HSQ-ZP after ALD of Pt. The inserts show the top view of the outer zones using the same scale bar as the tilted images. (f) Cross-sectional SEM view of the Pt-HSQ-ZP on an Si wafer substrate, observed with a tilt angle of 5°. |
