Sample Preparation Variables
- Angle lapping
- Ball cratering
- Blisters – break open with tweezers
- Carbon is often deposited by SEM
- Chemical derivatization
- Chemical etch
- Clean sample mount
- Clean with gas jet

- Cleanliness
- Contamination
- Damage can be caused by SEM
- Doping: n-, p- vs none
- Floating or grounded
- Fracture (in air, in LN2, under solvent)
- Glove bag (argon fill)
- Heating
- Horizontal traps
- In air – oxidation
