Oxides show fascinating functional properties ensuring their promising future in applications, e.g. flexible electronic devices. However, to generate flexibility, bulk single crystals and thin films on traditional substrates are incapable. Besides, direct fabrication on flexible substrates, such as organic polymers, is difficult due to extreme growth condition required for oxides, such as high-temperature. Recently, functional electronics were obtained on silicon by etching a sacrificial layer. The same strategy has been applied to obtain oxide sheets. For example, a freestanding perovskites oxide sheet of La0.7Sr0.3MnO3 (LSMO) was prepared by using a water-soluble oxide material, Sr3Al2O6 (SAO), as a sacrificed layer. However, very limited research on fabricating of perovskites oxide sheets and their transfer on flexible bases has been done to date. In this study, we synthesized SrRuO3, BaTiO3 and LSMO sheets by using SAO as a sacrificial layer and transferred them on various bases.
