Introduction

Dr. Huaixin Yang is the Group Leader of the A06 group at the Laboratory of Advanced Materials and Structural Analysis and the Director of the Academic Services Department at the Institute of Physics (IOP).

She received her Ph.D. from Taiyuan University of Technology in 2002. She was a postdoctoral fellow at the University of Exeter, UK (2002-2003) and at the Institute of Physics, Chinese Academy of Sciences (IOP, CAS) from 2004 to 2006.

She served as an Associate Professor at IOP, CAS from 2006 to 2011, and has been a Professor since 2011. She was appointed Director of the Academic Services Department in 2017 and became the leader of the A06 group in 2023.

Main Research Directions

1. Structural analysis of functional materials using electron microscopy and the study of structure-property relationships.

2. Development of ultrafast electron microscopy and the study of structural dynamics in functional materials.

Main Work & Achievements

Dr. Yang has long been engaged in the structural analysis of functional materials via electron microscopy and the study of their structure-property correlations. She has made a series of achievements in the multi-scale microstructural analysis and physical property correlation of layered materials, electronic ferroelectrics, and superconducting materials. In recent years, she has carried out highly effective work in the development of high spatiotemporal resolution ultrafast electron microscopy and the study of structural dynamics in functional materials. As a key member, she participated in the development of China's first Ultrafast Transmission Electron Microscope (UTEM), a fully domestically produced Ultrafast Scanning Electron Microscope (U-SEM), a Cryo-UTEM, and an aberration-corrected UTEM at the Huairou Science City. She has successfully implemented techniques such as ultrafast electron diffraction, ultrafast real-space imaging, ultrafast Lorentz microscopy, ultrafast electron energy loss spectroscopy, and photo-induced near-field electron microscopy in both stroboscopic and single-shot modes, achieving a series of important results in the study of ultrafast dynamics in several typical systems.

She was awarded the K.C. Wong Fellowship by the Royal Society, UK, in 2002 and the Young Scientist Award by the Chinese Society for Electron Microscopy in 2008. In 2013, she received the First Prize of the CAIA Award (China Association for Instrumental Analysis), and in 2014, she was awarded the Third Prize of the Beijing Science and Technology Award. She has published over 200 SCI papers with more than 5,500 citations and an H-index of 32.

Current Research & Outlook

1. Study of the structure and physical properties of novel functional materials. Using advanced TEM techniques to explore the intrinsic correlation between microstructure and physical properties in new functional systems such as high-temperature superconductors, multiferroics, nanomaterials, and topological quantum materials.

2. Development and application of ultrafast electron microscopy techniques. Our ultrafast TEM analysis platform can obtain structural information with high spatiotemporal resolution (femtosecond-angstrom). Using ultrafast electron diffraction, time-resolved imaging, and EELS techniques, we can directly probe atomic motion and changes in electronic states to conduct systematic studies of microscopic dynamics. Ultrafast electron microscopy and related techniques are currently in a period of vigorous development and represent a frontier in the field.

3. Synthesis and exploration of new superconducting materials.

Student Supervision

We plan to recruit 2 Master's students, 3 direct Ph.D. candidates, and 2 postdoctoral fellows. Candidates with backgrounds in physics, materials science, chemistry, and ultrafast lasers are welcome to apply.
