Research

Being member of ER-C2.

My research interest is in developing and applying the state-of-the-art TEM imaging and data analysis techniques in study of local atomic and electronic structures at surfaces, interfaces, and defects in materials, nanostructures, and devices. The ultimate goal of my research is to quantitatively determine local atomic and electronic structures, to elucidate their dynamics and influences, thereby, to understand materials properties and phenomena mechanisms at atomic level.

Some specific topics are below.

Methods and Techniques

• Quantitative spectromicroscopy with EELS, EFTEM, and EDX
• Quantitative (scanning) transmission electron microscopy
• Energy filtered transmission electron microscopy (EFTEM)
• Electron tomography
• Atomic resolution (S)TEM image processing, simulation, and quantification
• Spectral mixture analysis (SMA)
• Geometric phase analysis (GPA)

Materials

• Redox-based valence change oxides for resistive switching
• Ferroelectric oxides
• Phase-change materials
• Carbon-based materials
• Nanocrystals
• Smart alloys for future fusion power plants

Publications

Updated list of publication can be found on GoogleScholar, ResearcherID, ResearchGate, and ORCID.
