Extended Data Fig. 4: Electron tomography (ET) reconstruction of se-epitaxy composite.
From: Perovskite heteroepitaxy for high-efficiency and stable pure-red LEDs
a, Schematic of ET structure reconstruction. b, HRTEM image of a representative se-epitaxy composite. c-e, 3D reconstruction images for the representative se-epitaxy composite under various viewing angles. Inset: schematic illustrations of se-epitaxy composites. The reconstruction images reveal a complete nanoparticle in the blue region with size of 7.4 nm × 7.0 nm × 11.4 nm and a single-edge-attached nanoplate in red region, identifying as CsPbI3 QD/quasi-2D perovskite single-edge attached epitaxy (se-epitaxy).
