My research is in the field of strongly correlated electron systems and synchrotron radiations. This includes study of interplay of spin, charge, orbital and lattice degrees of freedom at interface and surface of novel complex systems and nanostructured strongly correlated electron systems, such copper-oxides, magnetic materials, unconventional high-temperature superconductors, diluted magnetic semiconducting oxides and two-dimensional electron systems.
We also work using synchrotron radiation in our own Singapore Synchrotron Light Source (SSLS) and around the world. Our team has pioneered a number of synchrotron-based experimental techniques, including resonant soft X-ray scattering, high-energy spectroscopy ellipsometry, and vacuum ultraviolet free electron laser (VUV-FEL) Raman spectroscopy.
Particularly at SSLS, we have recently constructed and built unique, state-of-the-art synchrotron-based characterizations consisting of resonant soft X-ray scattering, high-energy spectroscopy ellipsometry, and spin and angular-resolved photoemission spectroscopy. This new facility aims to be used explore new fundamental sciences as well as future applications in a broad range.
Some of works have been published in top journals including Science, Nature, Nature Physics, Nature Communications, Physical Review Letters, Nano Letters and Advanced Materials.
