TEM (Transmission Electron Microscope)
- Transmission Electron Microscope (TEM) is a high resolution analysis technique that allows one to see detail on an atomic scale.
- Samples are generally prepared until they are thin enough for electrons to penetrate through it to the detector.
- Coupled with EDX or EELS, quantitative information can be obtained.
- Another application of TEM is to make metrology measurements of crystalline, amorphous, etc., layers.
| Strengths | Limitations |
- High spatial resolution in nm |
- Most samples need to be specially prepared for analysis |
