Research Interests

PUSHING ONE STEP FURTHER SOME TEM TECHNIQUES
• Strain Measurement by using several different TEM techniques:
o High-Resolution Transmission Electron Microscopy (HR-TEM): development of a Geometrical Phase Analysis software (GEM-GPA)
o Convergent Beam Electron Diffraction (CBED): use of the stress relaxtion of the TEM lamella to compute the initial strain and stress
o High-Resolution Scanning Transmission Electron Microscopy (HR-STEM): with Pr. Jim Zuo, development of the Template Matching Analysis (TeMA and GEM-TeMA)
o NanoBeam Electron Diffraction (NBED)
o NanoBeam Precession Electron Diffraction (N-PED): development of a GEM-NPED software, adapted by FEI (now ThermoFisher Scientific) in their epsilon package.
o Scanning Moiré Fringes (SMF)
o Dark Field Electron Holography (DFEH): in collaboration with D. Cooper.

• Quantitative Analysis of High Resolution images: initially HR-TEM and now HR-STEM
• Development of Diffraction based techniques:
Coherent Diffractive Imaging (CDI)
and now starting ptychography and looking for students, PhD students and post-docs

MATERIAL STUDIES
• III-nitrides: polarity measurements, quantum dots aside dislocations, core-shell inversion domains in nanowires, strain around quantum dots, In segregation
• Si and Ge grain boundaries made either by Czochraski growth or by wafer bounding
• Phase Change Memory (PCM)
• Transistors: enhanced new strain measurements, measuring dopant concentration
• Nanoparticles: structure détermination
