Extended Data Fig. 2: Characterizations of interfacial crystal quality.
From: A fabrication process for flexible single-crystal perovskite devices
High-resolution TEM studies of transferred single-crystal MAPbI3 on different substrates (for example, gold for metals, glass for oxides and PDMS for polymers) using this growth-and-transfer method. The results show that there is no obvious lattice dislocation or polycrystalline structure formed at the interface, indicating that the re-adhesion/re-growth process maintains the single-crystal properties of the transferred materials.
