Name of Research Group:Electron Ultramicroscopy Group

Description of Research Group:Our group is dedicated to the interdisciplinary study of [sub-angstrom resoution S/TEM] and [advanced energy material]. This is substantiated by ultrahigh resolution light/heavy element imaging, spectroscopy analysis and in-situ biasing, heating, gas, liquid or cryogenic environment. Through performing cross-scale and multi-dimensional characterization and material growth, we aim to explore the intriguing and emerging structural phenomena and establish the structure-property relationship by combining AFM/PFM, in-situ XRD and other relevant techniques. the focus reserach directions cover:

[1] Temporal and atomic-resolution S/TEM imaging about light elements.

[2] In-situ TEM for AFE/FE energy storage and correlated physical property.

[3] Transient cryo-TEM for energy transfer and conversion in catalysts and batteries.

[4] Emerging polar phenomena in nonpolar quantum and alloy materials.

[5] 4D-STEM-based method, program and technique development.

Warmly welcome students interested in exploring the "micro-universe of matter" join us.
