论文摘要
金属卤化物钙钛矿单晶薄膜（SCTF）最近由于其出色的内在特性而成为下一代光电设备的有前途的材料。但是，由于其依赖底物的增长，将它们与混合多层设备的其他功能材料转移和集成在一起仍然是具有挑战性的。在此，允许将SCTF高质量转移到任意基板上的方法。通过对生长底物引入疏水处理，SCTF和生长底物之间的粘附降低。同时，使用抗溶剂插入技术可完整地从生长底物中剥离SCTF。最后，厘米级的钙钛矿SCTF已成功地转移到靶基板上。这项工作为转移大规模钙钛矿SCTF的新途径开辟了一条新的路线，提供了一个平台，以扩大大型混合多层光电设备中钙钛矿SCTF的应用。
Metal halide perovskites single-crystalline thin films (SCTFs) have recently emerged as promising materials for the next generation of optoelectronic devices due to their superior intrinsic properties. However, it is still challenging to transfer and integrate them with other functional materials for hybrid multilayer devices because of their substrate-dependent growth. Herein, a method that allows the SCTFs to be transferred with high quality onto arbitrary substrates has been reported. By introducing hydrophobic treatment to the growth substrates, the adhesion between SCTFs and growth substrates is reduced. Meanwhile, anti-solvent intercalation technique is used to peel off SCTFs from the growth substrates intactly. Finally, centimeter-scale perovskite SCTF has been successfully transferred to target substrate. This work opens up a new route to transfer large-scale perovskite SCTFs, providing a platform to widen the applications of perovskite SCTFs in large-scale hybrid multilayer optoelectronic devices.
