The technique can be coupled with Energy-Dispersive X-ray analysis (EDX) and Electron Energy Loss Spectroscopy (EELS) providing nanoscale elemental analysis and chemical bonding information. Detailed local crystallographic analysis (phase, orientation, defects and strain) is also possible.
Key Information
- Image area: 10 nm to 20 microns
- Resolution: 0.2 nm (High-resolution TEM; Lattice imaging)
- Bright-field & dark-field imaging
- Local elemental analysis using EDX and EELS
- Selected area diffraction
Common Applications
- Cross-section analysis
- Multilayer thickness determination
- Defect characterisation
- Interfacial layers (roughness, defects, bonding, ultra-thin layers)
- Local crystal structure determination and visualisation
- Semiconductor device imaging
- Polycrystal grain structure
- Nanoparticle and nanotube size, shape and structure determination
