Titan microscope

Caption: Probe corrected FEI Titan 60-300 kV at NCSU.

As scaling continues to be a major drive of research, future developments rely upon electron microscopy to probe the nature of material properties. In the nano-regime, one must explore local atomic structure, chemical composition, and bonding with ultimate spatial resolution. Now that aberration corrected microscopes have blown past the Ångström in resolution, a new level of clarity is available for exploring next-generation materials.

Research Interests

  • Application of aberration-corrected electron microscopy
  • Understanding material properties from the atomic structure
  • Reconstruction at the interface between dissimilar materials
  • Quantitative atomic resolution microscopy imaging and diffraction
  • Three dimensional imaging of materials
  • Image processing and analysis techniques
