Extended Data Fig. 7: Structural characterizations of the de-epitaxy composites.
From: Perovskite heteroepitaxy for high-efficiency and stable pure-red LEDs
a,b, Atomic-scale HAADF images of de-epitaxy composite with various particle sizes. c,d, Corresponding plots of octahedral tilting angle as a function of the [PbI6]4− unit cell across the CsPbI3 QDs (along the x-direction), with corresponding 95% confidence bands. The data presented as mean ± standard deviation of twelve [PbI6]4− unit cells in the y-direction.
