Recently, the research team led by Prof. Kehui Wu from Tsientang Institute for Advanced Study, in collaboration with Songshan Lake Materials Laboratory, has made important progress in the study of ternary molybdate polaritonic materials. Ternary metal molybdates with the general formula A₂(MoO₄)₃ (A = Al, Fe, Cr, etc.) host a wealth of exotic physical properties, including negative thermal expansion, ferroelastic phase transitions and elastic anisotropy. Strong optical phonon modes originating from MoO₄ tetrahedra inside the crystal lattice couple efficiently with mid-infrared photons, making this material family promising candidates for polaritonic applications.

Recently, researchers from the Acoustics Materials and Chip Team of Laboratory of Quantum Materials, in collaboration with Peking University, Songshan Lake Materials Laboratory, and other institutions, have achieved a significant breakthrough in the field of two-dimensional (2D) material-based acoustic sensing. They have innovatively proposed a pressure-assisted double transfer strategy for the constructing of large freestanding 2D material-based membranes. They have successfully fabricated centimetre-scale (largest of 8 cm) tensioned freestanding membranes with and a thickness of only 80 nm and a large D/h ratio (~106), and achieved pressure sensor and microphone with highly sensitive and excellent signal-to-noise ratio.

​Recently, the research team led by Professor Kehui Wu from Tsientang Institute for Advanced Study, in collaboration with Zhejiang University, Institute of Physics, Chinese Academy of Sciences, and other institutions, achieved a significant breakthrough in the field of functional oxide thin films. The related research findings, titled “Templated Perpendicular Ferroelectricity in Textured Aurivillius Oxide-based Thin Films,” were published in the top-tier international academic journal Nature Communications on March 13, 2026, with Tsientang Institute for Advanced Study serving as the primary institution.
