Research Area

Dr. Jing Li is a skillful microscopiest with most of TEM technology. Her research interests focus on the microstructural characterization and property-structure relationship in the fields of nanomaterials and other advanced materials using Transmission Electron Microscopy (TEM) and High-resolution Transmission Electron Microscopy (from theoretical to experimental). Her research is concerning:

  • Various nano-microstructured materials (nanocomposites (especially magnetic nanocomposites), nanoparticle self-assembly, core/shell structured nanoparticles, nanobelts, nanodisks, etc).
  • Highly disordered materials amorphous alloys, bulk metallic glasses, amorphous semiconductors, etc.).
  • A lot of alloys, super alloys, intermetallics.
  • Many other advanced materials.
  • Characterization for crystal defects (dislocation including the dislocation model and inner stress calculation in supperalloy, stacking fault, point defect clusters (small dislocation loops caused by ion irradiation), microtwins, etc.).
  • Study for the mechanisms of double Kikuchi envelopes ("double-parabola") in the reflection high-energy electron diffraction (RHEED) and convergent beam electron diffraction (CBED) patterns of gold and platinum single crystals by using computer simulation for the Bloch waves and dynamical electron diffraction theory.

Research Highlights

  • Characterization for the Nanometer scale interface between magnetically hard/soft phases with very similar crystal structure in magnetic nanocomposites poses a challenge. It has been characterized for FePt/Fe3Pt magnetic nanocomposite (self-assembly), confirming (from the view of microstructure) the realizing of exchange coupling between magnetically hard/soft phases in this magnetic nanocomposite. (A collaboration with IBM, published in "Nature").
  • Characterization for the magnetic nano-multiplelayers (interface condition, interface diffusion, etc.) is in process.
  • Characterization for the defects in amorphous materials is a challenge. Nanometer-scale defects (voids) have been characterized in the shear band of metallic glass by quantitative high resolution transmission electron microscopy and Fourier spectrum study, providing an experimental evidence for the theory of "increased free volume" within shear band in amorphous alloys (published in Phys. Rev. B).
  • Fluctuation electron microscopy, a new developed electron microscopy theory and method to study the amorphous materials, has been explored to characterize the medium-range order  structure in metallic glasses (published in Micros. Microanal).
