Figure 3. Complex nanostructures fabricated using SS-LZA.

(a) Large-area SEM of a three-layered hexagonal lattice with all-60° crossing angles (scale bar 1 μm), with FFT inset. (b) SEM of a Pt triangular mesh. (c) Rectangular Pt lattice obtained using two BCPs with distinct molecular weights (L_{0,first layer}=30 nm and L_{0,second layer}=51 nm); FFT of the low magnification SEM inset. (d) Oblique lattice (45°), constructed with the same BCPs as in c. (e) Mixed composition nanomesh with metallic (Pt) bottom layer and metal oxide (Al₂O₃) top layer. (Scale bars in b–e are 200 nm.)
