Fig. 3: Fabrication of high-quality QD architectures.
From: Chiral 3D structures through multi-dimensional transfer printing of multilayer quantum dot patterns
SEM images of nanostructures fabricated by mTP, representing single- to multi-layer (1 L–3 L) structures with different QDs: (a) CdSe, (b) InP, (c) PbS, and (d) ZnO. The SEM images highlighted with blue solid lines indicate PbS nanostructures stacked at tilted and inverted angles. Scale bars for the SEM images and the insets are 2 µm and 5 mm, respectively.
