报告摘要：

When artificially integrating the naturally incompatible atomic structures, crystallographic orientations and physical functionalities, the interplays at the interfaces induce unexpected functionalities, which is beneficial to future electronics in the aspect of manipulation, functionalization and utilization. However, realizing unrestricted heterogeneous integration and their electronic applications is extremely challenging, because of the technical restrictions of fabrication and the unwanted reduction of interface quality. The challenges are particularly severe in the heterogeneous integration of complex oxides with either other emerging materials or existing Si technologies, because of the incompatible growth dynamics and large lattice mismatch.

In this talk, I will discuss our experimental exploration of functional electronic devices based on the heterogeneous integration of perovskite oxide films. First, I will provide a brief overview of the emergent functionalities in oxide heterostructures and approaches to heterogeneously integrating the perovskite oxides. Then, I will discuss on experimental results of two related electronic applications based on the heterogeneously integrated structures consisting of perovskite oxide membranes and layered two-dimensional materials, such as energy-efficient transistors using SrTiO3 and multifunctional devices using Sr-doped LaMnO3. A summary will be provided at the end.
