Realizing emerging functionalities in oxide materials
Our research group focuses on the atomic-scale design and synthesis of functional thin-film materials using pulsed laser deposition. This technique enables the growth of high-quality epitaxial complex oxide thin films and heterostructures, allowing precise stoichiometric control and access to nonequilibrium growth conditions to stabilize metastable and coexisting phases with emerging functional properties.
To probe the structure-property relationships of these materials, we employ advanced thin-film characterization techniques, including synchrotron X-ray diffraction, scanning probe microscopy, and electrical property measurements. These techniques help us understand the structural and electronic properties of thin films, providing fundamental insights for designing new functional materials and devices.
A key area of our research is the fabrication and exploration of freestanding 2D oxide membranes. By selectively etching sacrificial layers, we release thin films from their rigid substrates, creating flexible and stretchable membranes that can sustain extreme strain states. These membranes offer new opportunities for strain engineering, dynamic property tuning, and heterogeneous integration, paving the way for novel device architectures and emergent functionalities.
Our work spans fundamental materials discovery to applied device engineering, with implications for oxide electronics. Through our expertise in thin-film synthesis, strain engineering, and advanced characterization, we aim to develop next-generation functional materials for energy applications, microelectronics, and quantum materials research.
