Seeking a Postdoctoral Researcher or Research Scientist (W24011)


Electronic States Microscopy Research Team
RIKEN Center for Emergent Matter Science
(Laboratory head: Xiuzhen Yu)

Research field

Our team is working on the real-space observation of electron structures or topological electron-spin textures and their dynamics in strong-correlation systems by means of atomic-resolution electron microscopy. We use various microscopy techniques, such as the electron tomography, in-situ imaging, differential phase contrast microscopy, electron energy-loss spectroscopy, and energy dispersive spectroscopy to explore the electron structures and their dynamical phase transition or phase separation. We also use these powerful tools to quantitatively characterize the nanometric magnetic and electric fields in topological matters to exploit emergent phenomena.
